Noise radar for range/Doppler processing and digital beamforming using binary ADC

Presently, there is an increasing interest in noise modulated radar. Wide-band signal processing with high range resolution, reduced ambiguities and high ECCM performance can be achieved. The processing involved correlates the received signal and the delayed reference. Range/Doppler processing and digital beamforming can be performed with surprisingly good results even for binary or a few bits ADC, if a second noise signal is added before.
