Phased array antenna with wide null

摘要: An antenna subject to standoff sidelobe barrage jamming exhibits a null in its structure at selectable elevation angle for all azimuth angles of interest. The can be set the corresponding jammers. is generated with aid an interferometer associated each column array. produces pattern having plurality lobes. phased and amplitude adjusted relative line array so that subtraction patterns causes one or more least partially canceled. beamformer combines arrays, connected own interferometer, produce pencil beam exhibiting particular angle.
