Abstract

An offset Cassegrain modified focal-pivot-scan monopulse antenna was designed for use with a 94 GHz search and track radar system which would be mounted on an armored vehicle. The focal-pivot-scan design provides for scanning of the main reflector about its focal point while the feed horn and subreflector remain fixed. This permits rapid beam scanning in azimuth for target acquisition while minimizing the mass that must be scanned (and the required scan motor capacity) and precludes the necessity for rotary joints with their attendant losses and possible mechanical failure. The elevation search function and tracking in both azimuth and elevation are accomplished using separate drive motors.
