A new methodology for interference/jamming suppression employing a spatial filter measurement matrix (SFMM) is presented. Different from the previous Capon beamforming method, the proposed method is not dependent on accurate prior information of targets’ directions‐of‐arrival (DOAs). The proposed SFMM suppresses the noise and interferences outside the searching area, thus apparently improves detection performance. The experimental results demonstrate the effectiveness of the proposed SFMM.
