Radar with a wide instantaneous angular field and a high instantaneous angular resolution in particular for a missile homing head

摘要

This radar with a wide instantaneous angular field and a high instantaneous angular resolution, in particular for a missile homing head, includes essentially:PPa transmitting antenna with a relatively wide radiation pattern, transmitting a quasi-continuous wave; PPa receiving antenna including a plurality of radiating elements;P Pmeans for formation of beams associated with said receiving antenna, to achieve a linear combination of the signals from the various radiating elements of said receiving antenna, in order to obtain a group of simultaneous reception beams allowing the instantaneous scanning of the airspace covered by said transmitting antenna.
