Patent ID: 6867731

Claim:
A noise suppression system for suppressing external interference in radar data provided by a plurality of sensors from a main sensor array, said radar data being pre-processed, said system comprising: a) a first processing module for receiving said radar data and producing matched radar data; b) a second processing module for receiving said radar data and producing mis-matched radar data; c) a beamformer in communication with said first processing module for receiving said matched radar data and producing beamformed matched radar data; d) an adaptive beamformer in communication with said second processing module and said beamformer for receiving a portion of said beamformed matched radar data and a portion of said mis-matched radar data, and producing an external interference estimate of the external interference in said portion of beamformed matched radar data; and, e) a suppressor in communication with said beamformer and said adaptive beamformer for producing a portion of noise suppressed beamformed matched radar data based on said portion of beamformed matched radar data and said external interference estimate.
