雷达极化抗干扰的本质是利用干扰与目标在极化域的差异，减弱或消除干扰对雷达探测的影响。极化抗干扰已经在主瓣干扰抑制、有源假目标鉴别、角度诱偏干扰对抗等抗干扰难题中显现出独特的作用。随着电子对抗水平的升级，目标与干扰间的差异呈现出细微化的特点，亟需进一步探索雷达抗干扰新技术，以充分挖掘和联合利用包括极化在内的各种差异。文章从发展历史、技术手段、典型应用等方面介绍了雷达极化抗干扰技术的研究进展情况。

The essence of radar anti-interference with polarimetry is to suppress or avoid the effects on radar exploring from the interference, by using the polarization difference between radar interference and radar target. Radar anti interference techniques with polarimetry has been applied successfully for several bottleneck problems, such as main-lobe interference suppression, decoy discrimination and anti angle deception jamming. Due to the upgrade of electronic countermeasure, the difference between interference and radar target echo becomes inconspicuous. As a result, it is imperative to research into the new radar anti-interference techniques which excavate fully and utilize synthetically all differences including polarimetry. Development history, key technologies, typical applications of radar anti-interference techniques with polarimetry are described in this paper.
