Advanced subspace projection method for interference suppression in phase array radar

Abstract

Abstract: As the dramatic development of the radar system, the phase array radar is widely used in military. There are more and more techniques adopted to improve the performance of the phase array radar. The most important part for the phase array radar is the ability to suppress the interference under the complicated electromagnetic environment with different kind of interference. In this paper, a novel method is proposed for interference suppression at the subarray level and the float round-off error for the proposed method is shown. The simulation results show that the proposed method has good performance.
