ABSTRACT:
A radar system comprises a transmitter that transmits a predetermined wideband signal, a digital receiver that records a returned signal using a one-bit ADC, a random noise source that is added to the transmitted or returned signal, a processing means where the received signal is distorted to compensate for the effect of the noise on the receiver. The predetermined wideband signal may be a pseudo random noise signal. The processing may include averaging prior to cross-correlation.
