ABSTRACT:
A processing method or algorithm is for use with a monopulse radar system that provides accurate position information in a cross-range direction for ground moving targets detected using the monopulse radar system. The method corrects the phase of each detected moving target on an individual basis, and thus more accurately compensates for the phase error introduced into each target in a random fashion as a result of noise. The direction of angle correction is determined from clutter data. A gain correction factor includes a term for antenna effects to provide for a more accurate gain correction factor calculation.
