Abstract
A method and system for suppressing unwanted signals when detecting objects of interest in a detection system comprising an antenna system and two or more receive beams. A background map is created by range, azimuth and Doppler. Locations within the residual clutter in the moving Doppler bins are selected for nulling. Adaptive nulling is performed independently on each Doppler bin of the selected location to enable Doppler-specific spatial nulling for the same range and azimuth bin.
