对制导雷达无源自卫干扰的效能评估及战术计算

Efficiency Evaluation and Tactics Calculation of Guidance Radar Passive Self-defensive Jamming

雷达干扰效能评估及战术计算是雷达对抗部队迫切需要解决却又缺乏系统研究的难题。为解决这一难点问题,针对制导雷达,运用解析法,首先建立了无源自卫干扰条件下导弹射击的预计次数、一次射击的杀伤概率及合成毁伤能力效能评估模型,然后给出了无源自卫干扰时一个雷达诱饵中反雷达反射体束的数量、连续投放的时间间隔及总消耗量等战术问题的计算方法,最后通过算例分析验证了模型的可行性和有效性,得出了具有实用价值的结论,可为空袭作战中作战效能评估、机载武器配备等提供参考。

The efficiency evaluation and tactics calculation of radar jamming is a puzzle that the troops of radar countermeasure have met and urgently need to solve but lack of system research.To solve this puzzle,the efficiency evaluation models of shooting degrees and kill probability against guidance radar under passive self-defensive jamming condition are established by analytical method,then,the tactics calculation methods of anti-radar reflector beam numbers,expending time interval and total wastage are also given.Finally,the effectiveness and feasibility of the models are illustrated with a numerical example and some valuable conclusions are reached,which can provide a reference for the operational efficiency evaluation and airborne weapon equipment.
