【摘要】: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。
[Abstract]:The essence of radar polarization anti-jamming is to weaken or eliminate the influence of jamming on radar detection by using the difference between jamming and target in polarization domain. With the upgrading of the level of electronic countermeasures, the differences between the target and the interference show the characteristics of nuance. It is urgent to further explore the new anti-jamming technology of radar in order to fully exploit and make joint use of all kinds of differences, including polarization, etc. In this paper, from the history of development, technical means. The research progress of radar polarization anti-jamming technology is introduced in typical applications.

【正文快照】: 0引言极化是描述电磁波矢量特征的物理参量,可用电磁波传播截面上电场矢量端点的运动轨迹来表征。例如,电磁波电场矢量端点的轨迹如果是一条直线,则称其极化为线极化(包括水平极化、垂直极化等);如果是一个圆,则称为圆极化,否则称为椭圆极化。雷达探测过程与极化密切相关,包括,
