2 Stable, Consistent Growth TSC Snapshot High technology company with focus on – Government, defense, commercial, international Founded in 1966 Employee-owned through Employee Stock Ownership Program (ESOP) since 1993 Small business, entrepreneurial culture 400 employees – 350 technical staff – 47% have advanced degrees FY 10 sales: $83.3 million Board of Directors includes Senior Defense Industry Representatives engineering services & technology development 2W265-092 / 15 September 2011

3 TSC Business Focus We design, develop, test and evaluate, and support Sensors, Decision Systems, and Weapon Systems and technologies for military and commercial customers We design, develop, test and evaluate, and support Sensors, Decision Systems, and Weapon Systems and technologies for military and commercial customers Navy Ship Combat Systems Sensor Simulations & Simulators Image Exploitation Enterprise GIS Solutions Sensor Modeling Integrated Logistics Support Advanced Sensor Concepts FAA Systems Prototypes & Production Army/USMC Systems 3W265-092 / 15 September 2011

4 TSCs Demonstrated Strengths Small, High Technology Company –World Class Engineers –Responsive to Customer –Cost Competitive Established Government Reputation as Trusted Agent or Honest Broker –System Design, Performance Assessment, Technology Insertion, Logistics –Expanded Services beyond Radar to Systems Engineering Capability Spans Program Life Cycle (Concept to Operations) –Ability to Provide Technical Life Cycle Continuity to Program Offices –Valued Technical Support: 30 Years Navy, 25 Years Air Force, 20 Years Army, 15 Years FAA –ISO 9001 Certified Prototype and Subsystem Production Capability Proven Ability to Assist the Government with Oversight of Major Programs –AEGIS, G/ATOR, ASR-11, Dual Band Radar Work Effectively with Large, Prime Contractors –Raytheon, Lockheed Martin, Northrop Grumman, Boeing 4W265-092 / 15 September 2011

5 RF Alliance Project Active Array Auto-Calibration 5W265-092 / 15 September 2011

6 6 Overview Of Array Technology And Calibration Active Phased Arrays Feature Many Active Circuits (i.e. T/R Modules) Operating In Parallel Behind The Various Elements Both On Transmit And Receive To Maintain Antenna Performance (i.e. Low Sidelobes and Accurate Beam Pointing), The Array Must Be Calibrated To Equalize Amplitude and Phase Variations Due To The Active Circuits –Initial Near-Field Range Calibration –Periodic In-Field Calibration A Practical Approach Is Needed T/R Modules A/D Receiver Array Elements W265-092 / 15 September 2011

7 7 Assessment of In-Field Calibration Techniques ApproachApproach Characteristics W265-092 / 15 September 2011

8 8 Path to Transition Array Features Array Features Necessary To Support Auto-Calibration Were Identified And Analysis Approach Defined With Examples. Relevant Array Features Include –Array Element Error Budget (Effects on Sidelobe Level and Beam Pointing) –A/D and LNA Linearity –Calibration Signal-to-Noise –External Echo Effects –Calibration Timing Array Features Identified Above Flowed Directly Into The Design of the Auto-Calibration Algorithm W265-092 / 15 September 2011

9 9 Path to Transition Modeling and Simulation Tool The Auto-Calibration Algorithm, Array and Signal Models, And Antenna Pattern Generation Were Integrated Into A Common M&S Tool –Supports different antenna architectures –Simulate calibration signal and utilizes measured data (amp/phs measurements, attenuator/phase shifter response curves, etc.) –Generates pre and post calibrated beam patterns M&S Tool Has Multiple Uses –Exercises algorithm under different array configurations and sizes –Refine algorithm and optimize parameters for an array under test –Support future demonstration and testing by incorporating measured data Auto-Cal Algorithm Simulated UnCalibrated Antenna Pattern Simulated Calibrated Antenna Pattern W265-092 / 15 September 2011

10 10 Path to Transition Demonstration & Future Plans TSC and RF Alliance Received Strong Interest From Navy To Conduct A Proof-Of-Concept Demonstration With An IWS Asset –Navy authorization was received and demonstration is expected to start in the fall Future Plans (Pending Demonstration Results) –Development of operational software package –Tailor operational software to candidate radar system –Fully test and quantify performance W265-092 / 15 September 2011
