ABSTRACT:
A range, angle, and Doppler (velocity) measuring radar in which a CW, PRC radar floodlights a volume of interest. A receiving antenna in the form of a linear array generally broadside with respect to the bisector of the volume of interest is commutated (sampled) element-by-element to provide a phase modulated received signal from which angle information may be derived. Autocorrelation of the PRC signal received against the transmitted code provides for range determination and a Doppler filter bank is provided corresponding to each discrete receiving angle, the outputs indicating range and velocity of a target at each discrete angle of reception.
