Contact the Electronic Warfare Division, Homeland Security Strategies GB RCIED stands for: Radio Controlled Improvised Explosive Device. In other words, an RCIED is an Explosive Device which utilizes a radio receiver as a detonation switch. Improvised means this Explosive weapon was not assembled in a factory, but put together in someone’s house, with commercial electronic parts such as car alarm equipment to mobile cellular phones.

4 The problem in dealing with RCIED weapons is that you do not know what type of RCIED that needs to be defeated (as in the case of cellular based triggers, wireless data based triggers, or RF spectrum detonators anywhere from low Megahertz to high Gigahertz frequency bands). You do not know the distance between the Trigger-Man and the RCIED’s radio receiver. You also do not know the power of the Trigger-Man’s transmitter. Understanding these basic ideas is vital, as once the defender acknowledges these issues (these unknown variables), one can prepare accordingly. Defining the Problem of Radio Controlled IED Weapons

5 Common IED Threats, their general bandwidth locations, and their respective frequencies where they reside.

6 Examples of IED Threats In order to understand how improvised explosive devices are put together, look at the components of this Car Alarm. Now look what happens when you remove the siren and replace it with an explosive payload and blasting caps. The commercial appliance has now been transformed into a deadly weapon.

7 Additional Examples of Commercially Available Electronics that can be built into an IED Threat CB Radios Cordless Phones Wireless Doorbells Satellite Phones Radio Controlled Toy Cars & Toy Airplanes Wireless PDAs Garage Door Openers Walkie Talkies (uhf & vhf radios) Keyless Entry Equipment Electronic Pagers & Restaurant Paging Equipment Business Radios Cellular Phones

8 ECM Jamming Systems: Countering the threat There are several RF Jamming technologies in use today. Electronic CounterMeasures are found to use multiple methods and techniques. They include: Swept Spectrum Jamming Swept Spectrum Jamming Barrage (Random Swept CW) Jamming Barrage (Random Swept CW) Jamming Intelligent Spot Jamming Intelligent Spot Jamming

9 Swept Continuous Wave Jamming Swept CW (Continuous Wave) is a jamming technique that can be explained in which the carrier frequency of the jamming is not noise-modulated, but only swept over the frequency ranges that correspond to the bands that could be used by radio triggers. In this technique, the exact frequency of the radio trigger does not have to be known ahead of time. Swept CW (Continuous Wave) is a jamming technique that can be explained in which the carrier frequency of the jamming is not noise-modulated, but only swept over the frequency ranges that correspond to the bands that could be used by radio triggers. In this technique, the exact frequency of the radio trigger does not have to be known ahead of time. If the band is relatively narrow, then the carrier need not be modulated to still be effective in jamming the receiver. However, this is usually not the case, and therefore, the jamming effectiveness of swept CW is greatly diminished when deployed over a wide bandwidth. If the band is relatively narrow, then the carrier need not be modulated to still be effective in jamming the receiver. However, this is usually not the case, and therefore, the jamming effectiveness of swept CW is greatly diminished when deployed over a wide bandwidth. The reason for this is that the sweep rate must be very fast in order to re-visit all the frequencies within the swept band. If the sweep rate is too slow, then the radio trigger can function between the time it takes for the sweep to return again to the same operating frequency or channel. The reason for this is that the sweep rate must be very fast in order to re-visit all the frequencies within the swept band. If the sweep rate is too slow, then the radio trigger can function between the time it takes for the sweep to return again to the same operating frequency or channel. But the fast sweep rate causes the jamming carrier to sweep past the receiver’s channel so rapidly that there is not enough time for the jamming signal to build-up to its maximum level as perceived by the receiver. This effect is particularly evident in communication receivers that have a But the fast sweep rate causes the jamming carrier to sweep past the receiver’s channel so rapidly that there is not enough time for the jamming signal to build-up to its maximum level as perceived by the receiver. This effect is particularly evident in communication receivers that have a Relatively narrow channel width or receiver “passband.” If the sweep is slowed down to allow more time for the receiver to respond to the jamming signal, then the re-visit time is increased, and that opens up the opportunity for the radio trigger to function (as mentioned). Significantly increasing the power of the jammer can balance to some extent the inevitable losses peculiar to swept CW jammers.

Significantly increasing the power of the jammer can balance to some extent the inevitable losses peculiar to swept CW jammers.

10 Spot Jamming is an effective technique, but only when the frequency or channel of the radio trigger is known in advance. The carrier frequency of the jammer is modulated by a random noise waveform to form a signal whose noise bandwidth overlaps that of the suspected signal transmitted over to the radio trigger. The noise interferes with the reception of the desired signal and prevents the bomb from being detonated. Spot Jamming is an effective technique, but only when the frequency or channel of the radio trigger is known in advance. The carrier frequency of the jammer is modulated by a random noise waveform to form a signal whose noise bandwidth overlaps that of the suspected signal transmitted over to the radio trigger. The noise interferes with the reception of the desired signal and prevents the bomb from being detonated. Unfortunately, this technique is only effective if the frequency is known absolutely and positively in advance, which is usually not the case. Attempts have been made to first detect and measure the frequency of the radio trigger in order that a jammer can be tuned or “set-on” to the frequency. Unfortunately, this technique is only effective if the frequency is known absolutely and positively in advance, which is usually not the case. Attempts have been made to first detect and measure the frequency of the radio trigger in order that a jammer can be tuned or “set-on” to the frequency. However, the extremely short time required to intercept, measure and set-on a spot-jammer to the frequency of the radio link signal - in the presence of many other legitimate signals across the frequency spectrum - make this an exceedingly difficult task.

Intelligent Spot Jamming

11 Barrage is a jamming technique that overcomes the problem of not knowing the operating frequency or channel of the radio trigger used to detonate the IED. It is similar to spot noise, except that the bandwidth of the noise- modulated jamming signal is made much greater in order to cover an entire communication band rather than just one channel. Barrage is a jamming technique that overcomes the problem of not knowing the operating frequency or channel of the radio trigger used to detonate the IED. It is similar to spot noise, except that the bandwidth of the noise- modulated jamming signal is made much greater in order to cover an entire communication band rather than just one channel. The carrier frequency of the jammer is modulated by a noise-like waveform to form a signal whose bandwidth fills the entire band with noise that is perceived by the receiver as interference. The carrier frequency of the jammer is modulated by a noise-like waveform to form a signal whose bandwidth fills the entire band with noise that is perceived by the receiver as interference. The disadvantage of Barrage Noise is that the noise is spread over such a large spectral bandwidth that its jamming effectiveness is degraded, yet this is compensated for by increasing the RF power output of the jammer from hundreds of watts to even thousands of watts.

Barrage Jamming is typically effective against very low-powered transmitters that are located at distances far from the IED. It may also be effective against narrowband frequency ranges.

12 Protection Distances Is the terrorist using a GSM Cell phone or a 2 Watt FRS 2-Way Radio? Did he modify his 2 Watt Radio in to a 5 Watt Radio? You don’t know! Neither does ANY Jammer Manufacturer! The only way to effectively defend against this threat is with a barrage type jammer with brute force to jam the receiver from receiving the enemy signal to detonate. Many Jammer manufacturers give a “Protection Distance”. There are many unknown, uncontrolled variables such as enemy transmitter power, distance between transmitter and receiver, and distance between jammer and RCIED. Therefore, it is impossible to calculate an actual “Protection Distance”. Testing distances under controlled conditions are the ONLY values which can be validated for protection distances.

13 Distances (continued) However, the BombJammer™ VIP Systems have been tested against multiple threats at controlled distances and output powers. RCIED Transmitter with unknown power output UNKNOWN DISTANCE AND OUTPUT POWER As previously stated, no distance can be guaranteed as a result of multiple factors which are beyond control.

14 The following are typical results achieved when testing known threats against a BombJammer™ VIP 500 Series. SUMMARY All unmodified threats on frequencies from MHz (No breaks) are EFFECTIVELY JAMMED when tested at 250 Meters on average with jammer at center point between RCIED Receiver and the Enemy Transmitter.

15 RCIED Jammers: Users & Missions RCIED Jammers are used in: Convoy missions Facility installations Perimeter borders Convoy Security: Drivers of vehicles switch them on to protect from Roadside Bombs. Drivers switch them off to communicate, unless they initiate a BombJammer™ utility with sub-band ‘windows’ or notches in the RF Jamming Spectrum to exchange brief voice or data broadcasts. Facility Jamming: To prevent terrorist / insurgent attack on Government controlled buildings, RF Jammer shielding is implemented to combat RCIED and Suicide Bomber attacks using hand-carried Radio Triggered weapons. From embassies, military camps – barracks, as well as commercial locations where people are targeted are all areas to be defended against attack by RCIEDs. Perimeter borders: Because terrorists target people in transit, the safety of a border crossing is no exception. Checkpoints within or adjoining hostile environments where the rule of law may be challenged by bands of individuals on route to commit attack by RCIED deploy BombJammer™ configurations. Solutions involve stationary and mobile units.

16 Users & Missions: Who Decides what type of Jammer to Deploy? BombJammer™ RF Jammers are designed to defeat many types of threats. However, Jammers are also ordered to be constructed to the specifications of Procurement Groups, generally untrained in RCIED Defeat. When buyers compare RF Jammers from one manufacturer to another, the result is rarely a proper comparison, as price, not theory of operation, generally determines which system is the one for the mission. The only qualified buyer of an RF Jammer used to keep those safe from RCIED threats would be one who has undergone the proper EOD education on Countering IED threats. In most instances, BombJammer™ training is available at the production facility for one reason only: When a buyer learns from the engineering officers who build the systems operating in the field, they gain a better intelligence level on what to expect, the inter-relationship between the jamming equipment and physics involved, and what type of Jammer is the one for the mission at hand.

17 Open-Ended Architecture All BombJammer™ VIP Systems are of modular design and open-ended architecture. This ability allows for addition of modules for future RF threats of higher frequency. The modular design of the BombJammer™ systems allows for continued operation of unaffected modules should a module fail or be destroyed. Most other jammers become non-functional should a failure occur.

18 Jammer Variations There are 3 Types of BombJammer™ variations. What follows are a brief collection of some of the models designed for use in multiple environments by multiple users: Vehicle Mounted BombJammer™ Vehicle Mounted BombJammer™ Transportable BombJammer™ Transportable BombJammer™ Stationary BombJammer™ Stationary BombJammer™

19 Model VIP-300T BombJammer™ is a modular Electronic Countermeasure System for covert operation, designed for defensive jamming of Radio Controlled Improvised Explosive Devices (RCIEDs). VIP-300T COVERT IED JAMMER — TRUNK MOUNTED VERSION The BombJammer™ VIP-300T uses proprietary RF technology to transmit Fast Randomly Swept Continuous Wave (CW) signals that interfere with the operation of radio-controlled links used to detonate explosives such as roadside bombs. This multi-band jammer is comprised of seven (7) modules that jam all known RCIED threats in the frequency range of 20 MHz to 2500 MHz. Specific threats include VHF and UHF Radios, Long-Range Cordless Phones, Cellular Phones, Satellite Phones, Remote Control Devices such as RC Models and Wireless Actuators, Pagers and Portable Radios— Walkie-Talkies. The BombJammer™ VIP-300T provides contiguous spectral coverage from 20 to 2,000 MHz and from 2,400 to 2,500 MHz; thus creating an intensive barrage of interference over seven (7) frequency bands. The target is thus protected against attack from RCIEDs by preventing the detonation of the associated explosive bomb. The system is suitable for mounting inside any vehicle’s cargo area or within the trunk. It is powered directly by the existing 12-volt automotive electrical system if equipped with a high-output alternator.

20 When additional spectral coverage is required for unforeseen threats, the VIP- 300TE is required. Providing an extended RF Jamming envelope, the VIP300TE exudes electromagnetic interference using a full force barrage of energy in a manner that attacks radio waves at the receiving end to counter a radio triggering device from receiving signals. Designed as the next level from the VIP300T series, the VIP300TE offers RF Jamming starting at 20MHz through 6,000 MHz for the reason that there does exist threats at the higher spectrum. Although those threats are limited, they still exist and the VIP300TE is able to target those dangers from receiving an RCIED detonation signal. VIP-300TE High Power Barrage Jammer The High Powered Jamming System can also be deployed in an Armored SUV System Architecture is designed to counter RCIED threats of commercially available radio electronics found in IEDs, Sattelite Phone & Cellular IEDs, Long Range Cordless Phone IEDs, and other known threats (and future unknown threats)

21 The VIP 500 was built with modular system architecture to meet the changing tactical and operational threat environment: Band-specific modules for threat specific coverage enabling a high spectral power density and effective jamming radius Multiple matched antennas for higher radiation efficiency This is a multi-band jammer with extended abilities that interferes with signals in the frequency range of 20 MHz to 6 GHz. Including most current threats including cell phones, walkie talkies, and satellite phones. Using this unique technique, the Bombjammer™ VIP 500 creates intensive barrage interference within the whole frequency range and at the same time amplifies the jamming signal on the 6 narrow frequency channels which makes it more effective against the use of walkie talkies and cell phones – known devices utilized by terrorists for remote control detonation. The system is suitable for mounting on any vehicle. The VIP-500 is one of a series of jamming systems that offers protection against radio-controlled roadside bombs to VIPs and Military and Government Personnel. By effectively emitting a protective shield of electromagnetic radiation, the target is protected against a terror attack with a remote controlled improvised explosive device (RCIED). VIP-500 HIGH POWER BOMBJAMMER™ (ROOF MOUNTED)

22 The VIP-300C is a vehicle mounted Communications Jammer. This Com Jammer provides communication jamming within the range of 20MHz - 2,500MHz on the RF Spectrum without any frequency gaps, ensuring complete and continuous RF jamming to attack all respective communication bands. The VIP300c Com Jammer has successfully eliminated the use of a Laptop for programming & operating. (Traditional RF Jammers are deployed with a Laptop for programming of RF threats to be defeated. ) The VIP300C has its own interface built in for Field Programming, with SELECTABLE TUNING of communication bands deemed to be threat sources without the need for factory adjustment. This provides greater accuracy and ease for battlefield communication jamming, as well as RCIED Defeat. VIP-300c Communications Jammer

23 VIP-900 STATIONARY RF JAMMER for Buildings, Barracks, Checkpoints The VIP 900 was designed for buildings, checkpoints, border crossings, security gates, force protection barracks, and environments that restrict radio frequency traffic that might be used to trigger radio detonators of explosive weapons. Our technology is configured in modular components in order to regulate a continuous broadcasting format of radio interference. This interference overpowers radio receivers used to detonate remote controlled IED weapons from receiving their detonation commands. The RF Jammer helps secure and protect people in and by office buildings, embassies, consulates, and border crossing checkpoints from terrorist activated remote controlled bombs that are generally built as Improvised Explosive Devices. IED’s are simple to build and thanks to the BombJammer ™ line of RF Jammers, able to be defeated. The Stationary RF Jammer may also be used to protect homes, schools, convention halls, public buildings, hotels, and other civilian gathering places used targeted by terrorists. The Bomb Jammer ™ VIP 900 uses sophisticated RF technology and transmits radio interference signals that spread out, saturating the spectrum of radio frequencies in order to block trigger devices from activating remote controlled explosive bombs. The jamming has no dangerous effects on normal vehicle electronics, computer, telephone or other office equipment functions.

24 This is a transportable system. As such, it can be moved from vehicle to vehicle, and does not need to be temporarily or permanently installed in a vehicle. The Transportable RF Jammer incorporates optional jamming modules for extended frequency coverage as well as increased output for optimum RF jamming. To activate jamming, it takes about 1 second to turn on the system switch. When this Radio Jammer broadcasts electromagnetic interference using extended frequencies, the chance of detonating a roadside bomb or radio controlled mine are reduced. This Radio Jammer yields additional power output to increase the level of protection around the area of deployment in order to jam radio receivers of a remote controlled IED, especially if the radio transmitter happens to be located in close proximity to the radio receiver/ radio detonator. Using Radio Jammers with an expanded architecture helps to cover both known and unknown threats in VHF, UHF, and Microwave frequency ranges. Expanded architectural design provides for the dealing with future threats as they arise and as determined by the user. By adding jamming modules, the power output can be increased, offering increased saturation of the electromagnetic spectrum. VIP-300U TRANSPORTABLE RF JAMMER The Transportable RF Jammer model VIP300U uses a proprietary barrage jamming method to defeat remote controlled improvised explosive devices. It works by sending out RF Jamming signals to jam radio receivers while in motion or standing still.

25 VIP-200M Portable RF ECM JAMMER (Briefcase Version) ECM Jammers such as the VIP 200 is a hand held Bomb Jammer ™ built into a briefcase. It transmits RF interference to block radio receivers found in a Cellular IED, Satellite Phone IED, Mobile IED, and other Radio IED triggers from obtaining any RF signals, and is vital to preventing an RCIED or Remote Controlled Improvised Explosive Device from receiving a detonation signal. This hand carried RF Jammer neutralizes the RF Signal or detonation signal as a result of increased saturation of RF interference it transmitters. RF Jamming using the portable RF Jammer gives the user the edge when trying to avoid an attack from a Remote Controlled IED. Specific IED ambushes involve a terrorist or insurgent transmitting a detonation command from a landline or cellular phone to a Cellular IED, Mobile IED, or Satellite Phone IED. In these instances, the phone is connected to an explosive and is detonated on command by someone who can generally see if the victim is within range of the IED. Other instances involve a Radio Controlled IED that receives an RF detonation signal from a trip-wire, motion sensor, or other automatic trigger that the victim unknowingly activates. The RF transmission to the IED, therefore, can be unmanned and cause the IED to operate as a remote controlled land mine or radio fired mine activated by an RF signal. The VIP 200 Bomb Jammer ™ can neutralize that threat. The VIP 200 Bomb Jammer ™ is built into a briefcase and may be carried as such. It transmits RF interference, whether the user is moving or standing still. The VIP 200 Bomb Jammer ™ jams the signals of unauthorized transmitting devices used to activate explosive weapons. Users range from government officials, government contractors, mine clearance personnel, diplomats, dignitaries, etc.

26 VIP-250PC Cellular COM JAMMER (non-BombJammer™) This is a portable, lightweight RF Jammer, that can jam cellular phones in office buildings as well as outside on the ground. It can be moved from vehicle to vehicle, and requires no vehicle installation. The Cellular Com Jammer is the perfect choice for restricting cellular phone users in CONFERENCE ROOMS to contain private and confidential information. The Cellular Com Jammer is also used by SWAT Teams, Hostage Negotiators, and Tactical Response Agents who need a field portable Jamming system to defeat criminal communications. The Cellular Com Jammer is designed to cover all cell phone frequencies: GSM 800/900, DCS/PCS/GSM1800, 3GPP as well as alternate wireless frequency bands such as b (WiMAX, WiFi). This is a User friendly Communication Jammer, easy to operate, requires no special training to work. The modular configuration allows the user to choose the frequency bands according his needs. Should one module get shot by weapons fire and fail, all other modules will still operate, as they are independent of one another. The VIP-250PC has a built in system that provides feedback of operational status in real-time, with low voltage protection and protection “by fault start”. The system’s architecture is scalable, allowing additional communication bands to be selected and incorporated should the user require.

27 VIP-300DS Programmable Barage Jammer) With an Output Power greater than 200W (our base version), and extensions up to 300W available, the Programmable Barrage Jammer is a likely choice for those seeking a multi-band jammer with higher EM saturation levels. The VIP 300DS can be field programmed to allow "windows" for communication as required. The system is suitable for mounting inside any vehicle's cargo area or within the trunk. It is powered directly by the existing 12-volt automotive electrical system if equipped with a high-output alternator. The VIP-300DS is one in a series of the new generation of programmable jamming systems that offers protection to VIP’s, military, and government personnel against the continued threat of terrorist acts. Covert Antenna: For discreet ECM Missions, our proprietary covert antenna with heavy duty magnet mounts can be placed on top of the vehicle and withstand vehicle high speed travel. Additional Features: Unlimited Operation Time with engine running No modification required of the vehicle’s electrical system Allows for installation between vehicles Antennas and wiring harnesses can be pre-installed to allow easy exchange between vehicles

28 With our Man-pack Barrage Jammer VIP600, the user can take operate a portable ECM Jamming system in the field while moving or standing still.
