2. Introduction & Motivation
Radio Frequency Signal
3kHz - 300GHz (Telecommunication , GPS, Wifi, Radar Signal)
Radio Frequency Interference
Degrading signal quality.
How to find interference (RF Energy)
Arecibo Radar
430MHz, L band (1GHz - 2GHz)

3. Software Defined Radio(SDR)
Hardware is needed for the RF front end, ADC(Analog to Digital Converter) and DAC(Digital to Analog Converter)
Radio Receiver
Why RTL2832U?
Low Cost $15
Frequency range
(24kHz MHz)

4. How to collect the data? Use SDR to get the radio frequency signal
Use Gqrx SDR to find the interested frequency
Collect data using SDR
Open the collected data in any data processing software, like Matlab
Plot the Fourier Transform and analyse the data

7. Summary Tasks implemented
Selecting SDR meeting technical specifications
Acquiring Data using SDR
Applying FFT to raw data using MATLAB
Future work
We are going to implement an algorithm on the SDR in real time detection
GNU radio
Python
