This study presents an innovative algorithm to extract binary data from a high frequency linear chirp signal contained in wideband radar pulse signal. The algorithm is designed for chirp signals (bandwidth of 125 - 1375 MHz) with a maximum chirp rate of 750 MHz per 100 ns and a maximum chirp range equivalent to the signal bandwidth. Additionally a maximum bit length of 64 bits and a SNR range of -20dB - 20dB is used. These parameters are randomized and used to generate the chirp signal… CONTINUE READING
