雷达诱饵对空空导弹对抗干扰效果分析

在复杂电子对抗条件下，采用伴飞诱饵对雷达制导空空导弹进行干扰可以有效地提高载机的突防和生存概率。为一次得到在干扰下空空导弹脱靶量与时间的关系，分析诱饵对空空导弹干扰的对抗过程，创新性的采用伴随方法建立了诱饵作用下空空导弹末制导伴随模型，并通过放真程序进行仿真得到对抗过程中各种条件下的空空导弹末制导脱靶量，结果表明，载机在合适的时间投放诱饵并机动能够引起较大脱靶量并降低空空导弹对载机的威胁程度，证明了伴随方法的有效性并为伴飞诱饵的应用提供理论依据。

Analyses of Jam Effect for Radar Decoy in Endgame of Air to Air Missile

Under the condition of the complex electronic countermeasure, it can effectively improve the penetration and survival probability of the fighter plane using radar decoy flying with it to interference the radar guided air-to-air missile interference. In order to get the relationship between air-to-air missile miss distance and time under the interference of radar decoy, this paper analyzes the combat process of the interference of the radar decoy for air-to-air missile, establishing the adjoint model of the terminal guidance of air-to-air missile with the interference of radar decoy, and gets the miss distance of the terminal guidance of air-to-air missile once in all situations of the combat process through the simulation software. The result shows that the fighter plane bait the radar decoy at the right time and manoeuvers will led to large miss distance and reduce the degree of air-to-air missile threat to aircraft, which proves the validity of the adjoint method and provides a theoretical basis for the application of radar decoy.
