ABSTRACT:
This disclosure relates to an improved airborne monopulse radar system used for tracking ground targets. The system includes a null command generator designed to provide an error signal proportional to the angle between a preselected target azimuth and the monopulse antenna difference pattern null azimuth which error signal is unaffected by the presence of moving targets within the area under radar surveillance. The error signal is applied to the monopulse antenna drive servomechanism in order to physically reorient the antenna to have the difference pattern null and the preselected target aligned along the same azimuth.
