照射箔条复合干扰对抗空空雷达主动弹方法

照射箔条复合干扰相比传统无源箔条干扰可提高战机自卫干扰能力,提高战场生存能力。为研究照射箔条复合干扰对空空雷达主动弹的干扰效果和战术使用策略,在一种典型空战对抗态势基础上,从速度干扰条件出发,对照射箔条复合干扰相对传统箔条干扰在频率特性上的优势进行了理论分析。在此基础上,提出在对抗空空雷达主动弹中,通过对转发干扰信号进行频率调制,并与载机机动配合的方法,增强复合干扰对雷达导引头的速度欺骗干扰效果。仿真结果表明:该方法可以起到良好的速度干扰效果,该方法具有较强的实践指导意义。

A Study of Compound Jamming in Counter Active Radar AAM Based on Radiating on Chaff

Compared to the traditional passive chaff jamming, the radiating on chaff compound jamming can enhance ability of self-defense and survival capability of fighters in battlefield. In order to study the jamming effectiveness and strategy of radiating on chaff compound jamming in countering active radar AAM, by using a typical air battle situation model, this paper, based on velocity deception condition, analyzes the advantages of compound jamming over the traditional passive chaff jamming in countering active radar AAM in frequency. The paper proposes a method of frequency modulation in cooperation with fighter''s motion to greatly enhance the efficiency of compound jamming velocity deception on active radar seeker. The simulation results show that this method is efficient in velocity deception jamming, the effectiveness of this method is verified, and has a guiding role in practical air battle.
