| 摘 要： | 现有抗距离拖引干扰方法通常从时域或者频域特性差异来进行干扰的识别与抑制,随着数字射频存储技术的发展,干扰机模拟的干扰信号与目标信号在时域、频域的相似度越来越高,必须探索其他途径来提高雷达的抗干扰性能。根据距离拖引干扰过程中跟踪波门内信号极化特性的差异,研究了一种距离拖引干扰的极化识别与抑制技术,通过仿真说明运用极化信息能较好地解决距离拖引干扰的识别与抑制,拓宽了雷达抗距离拖引干扰途径。

| Abstract: | The existing anti-RGPO methods are based on the time domain or frequency domain charae teristic differences. With the development of digital radio frequency memory, interference signal simulated by jammer becomes more and more similar with the target signal in time domain and frequency domain. Other ways to improve the anti-jamming performance of terminal guidance radar must he explored. According to the polarization characteristic differences of signal in the tracking gate when RGPO is processed, a kind of polari zation identification and suppression technology of RGPO is researched. The simulation shows that the identi fication and suppression of RGPO can be better solved by use of polarization information. The way of termi- nal guidance radar anti-RGPO is expanded. |
