Abstract:
1. A method for independently setting range resolution, Doppler resolution, and pulse compression processing gain in a pseudo-random coded Doppler radar comprising: generating a pseudo-random code (PRC); generating a segmented PRC by dividing said PRC into a plurality of PRC sequences; generating a spread segmented PRC by spreading the said PRC sequences of said segmented PRC apart in time; transmitting said spread segmented PRC into a surveillance area; receiving a target signal comprised of reflections from radar targets in said surveillance area due to said transmitting of said spread segmented PRC; generating a bank of matched filter outputs by passing said target signal through a plurality of filters where each filter is matched to a different Doppler shifted version of said spread segmented PRC; and detecting moving targets in said surveillance area from said bank of matched filter outputs.
