摘要
A system for adaptively generating a sidelobe null in a radar transmit antenna pattern by positioning a small air vehicle along the radial of the sidelobe to be suppressed. The air vehicle is fitted with a receiver and antenna facing the radar, as well as a GPS device for maintaining the designated position. The vehicle further includes a communication link to the processor of the main radar transmitter to form a closed loop that enables adjustment of the attenuators and phase shifters of the auxiliary channel(s) to suppress signals transmitted in the sidelobe to be nulled. The com link may be replaced by a suitable transponder.
