An Anti-jamming Method Based on Convex Optimization for Dual Polarized Conformal Array

Abstract

Beamforming is a promising technique for suppressing interferences and enhancing desired signal in communication system. However, when the interference is close to the desired signal, the performance of the traditional beamformer decreases sharply. In this paper, a novel space-polarization joint domain beamforming algorithm is proposed to suppress the main lobe interference based on dual polarized conformal array. The proposed beamformer is designed by using convex optimization constraint criterion, which integrates the space and polarization information of the signal and can suppress the interference of arbitrary space and polarization parameters. The simulation results show that the proposed algorithm provides good performance even if the interference and the desired signal come from the same space angle.
