Title:
ADAPTIVE DIGITAL BEAMFORMING RADAR METHOD
Document Type and Number:
WIPO Patent Application WO2003023436
Kind Code:
A3
Abstract:
A method and system for are provided for detecting one or more radar targets of interest in the presence of jamming signals. A plurality of sub-arrays are formed from an antenna array. Sub-array beams are adaptively formed so as to point one or more nulls in one or more respective directions corresponding to one ore more jammers. A super-resolution technique is applied to determine a count of the one or more radar targets and to determine the corresponding direction of arrival.
