The performance of the adaptive beamforming is vulnerable to the DOA mismatch, especially in the case that the power of the desired signal is large enough compared with the interference. This phenomenon is called “self-nulling”. In addition, the desired signa l is mitigated and the beamformer catches the interference whose power is larger when the blind beamforming algorithm is employed based on the constant module property. A new beamforming algorithm is presented so that beamformer could work well even if the dynamic range of the interest signal is considerably large. In the new deployment, the DOA information and constant module property of the desired signal are both used. The implementation of the proposed algorithm is presented and the array gain is analyzed. Simulation results show that the main lobe of the array antenna is steered to the desired signal and the interferences are suppressed in the the assumed condition.
