一、前言 由于电子对抗技术的迅速发展,雷达系统已不可能在无干扰的战斗环境中工作。在现代化战争中,没有抗干扰设备的雷达非但无用,反而会暴露自己,甚至被敌方摧毁。因此,提高雷达的抗干扰能力是雷达当前急待解决的一个重大课题,雷达的极化捷变技术就是雷达抗干扰措施中的一个。 对雷达的干扰措施一般有积极干扰和消极干扰两大类: I. INTRODUCTION Due to the rapid development of electronic warfare technology, the radar system has been unable to work in an undisturbed combat environment. In the modern warfare, radars without anti-jamming equipment were not only useless but instead exposed themselves and even destroyed by the enemy. Therefore, improving the anti-jamming capability of radar is an important issue to be solved urgently by the radar. The polarization agile radar technology is one of the radar anti-jamming measures. Interference measures to the radar generally have two kinds of positive interference and negative interference:
