噪声干扰对主被动复合导引头失效机理分析

Failure Mechanism of Noise Jamming for Combined Radar Seeker

近年来,一些新的雷达抗干扰技术的出现,对传统的干扰技术构成了严峻的挑战,在试验中出现了一些常见的干扰方法对特定雷达干扰失效的情况。故分析干扰方法失效机理,对改进干扰方式、升级干扰装备具有重要的意义。以自卫式噪声干扰对主被动复合导引头干扰失效为例,首先介绍了主被动复合导引头工作原理,接着分析自卫式噪声压制干扰对主被动复合导引头失效原因,而后建立噪声干扰信号模型,并利用导引头仿真平台,进行攻防对抗仿真,验证理论分析的结果。

In recent years,the emergency of some new technologies of radar counter-counter measure （ECCM） has posed a threat to traditional jamming technology severely, and some jamming methods fail to jam specific radar in the same experiment. As a result, the analysis of failure mechanism means a lot to improving jamming method and weapon equipment. Based on the working principle of combined radar seeker, the failure causes of self-protection noise blanket jamming to combined radar seeker are analyzed and discussed, and then the model of noise blanket jamming signal is established, a simulation of attackdefense confrontation is carried out by using the platform of combined radar seeker, and the result of the theoretical analysis is verified.
