摘　　要：压制式干扰往往会使相控阵雷达系统失去其基本探测功能。针对此问题,利用正交极化失配的原理,将干扰信号源在接收端进行极化隔离,由此提高极化相控阵雷达的抗干扰性能。提出极化域-空域联合波束形成技术,推导了旁瓣极化与零陷约束联合优化的最优极化波束形成的优化问题,将优化问题转换为SOCP(二阶锥规划)问题进行求解,最终得到具有旁瓣零陷和极化约束的极化波束。仿真结果验证了算法的有效性。Oppressive jamming makes phased array radar incapacitate its normal detection function.For this problem,the basic polarization mismatch is used,the interference source is isolated at the receiver,and the anti-interference performance of the phased array radar is improved. A joint beamforming technique for polarization and spatial domain is proposed,the optimization problem of optimal polarization beamforming is derived,and the problem is converted to SOCP problem,then the polarized beam with sidelobe null and polarization constraint is obtained. The simulation results demonstrate the effectiveness of the proposed approach.
