摘　　要：针对传统抗主瓣干扰方法性能有限,且单站雷达获取信息维度低的问题,提出一种网络化雷达极化域主瓣压制式干扰抑制方法。首先对不同极化方向的各节点回波信号进行建模,然后通过节点回波信号的加权对消、匹配滤波实现极化域抑制主瓣压制式干扰,最后通过仿真验证了其有效性。In view of the problem that the performance is limited for conventional anti-main-lobe jamming methods and the dimension of acquiring the information from the single-station radar is low,a main lobe blanket jamming suppression method is proposed in the polarization domain for the networked radar.Firstly,the echo signals of each node are modeled with different polarization directions,and then weighted cancellation and matched filtering are used to suppress the main lobe blanket jamming in the polarization domain.Finally,the method is verified to be effective through the simulation.
