摘要
针对双极化雷达缺乏工程可实现的极化抗有源干扰方法这一问题,提出一套完整的极化抗干扰处理流程,首先综合采用极化度和极化比,实现有源干扰信号鉴别,再采用极化比平均方法实现多通道极化滤波处理。实际电子对抗结果表明,该方法干扰鉴别准确,能有效对抗压制干扰和欺骗干扰,干扰抑制比可达到20dB;满足后续SAR成像和单脉冲跟踪的处理需求。
In order to solve the problem that dual-polarization radars lack the engineering meth-od of polarizing anti-active interference,a complete set of polarizing anti-interference processes is proposed.Firsly,the wave degree of polarization and polarization ratio are presented to identify active jamming.Secondly,polarization ratio averaging method is used to achieve multi-channel polarization filtering.The results of the electronic confrontation shows that the method has the ca-pability to identify and suppress the suppressing and repeater jamming,and the interference sup-pression ratio can be up to 20dB.The processed data can meet the needs of SAR imaging and tracking.
