Abstract
A CW pseudo-random-coded (PRC) radar system including a triple-clock arrangement. The three slightly different clock frequencies are sequentially employed to generate the bi-phase coded RF transmissions and the received echo signals are separately bi-phase de-modulated by code bit. Clutter filtering and sampling in both I and Q channels by a commutating element are employed. Video processing, preferably of the FFT type, is provided as is range-ambiguity processing. The system provides resolution of range ambiguities over a long total range permitting the PRC word length and other system parameters to be optimized for elimination of Doppler ambiguities.
