箔条干扰条件下舰空导弹单发杀伤概率计算

摘要

Higher and higher requirements are put forward to the antijamming ability of missiles,and the single continuous fire kill probability under chaff jamming conditions has been a key index to evaluate the capability of missile.Aiming at testing thesingle continuous fire kill probability of ship to air missile under chaff jamming conditions,a radar seeker receiving terminal signal to interference ratio (SIR) model,a round shaped target falling into probability computing model of ship to air missile and an antijamming improvement factor model are built respectively.And then thesingle continuousfire kill probability model of ship to air missile under chaff jamming conditions is given.With this model,the true and effective single continuous fire kill probability will be calculated.%目前,对导弹抗干扰能力的要求越来越高,干扰条件下的导弹单发命中概率已成为评定导弹性能的重要指标.针对箔条干扰条件下舰空导弹单发杀伤概率评定,建立了雷达导引头接收端信干比模型、舰空导弹圆目标落入概率模型以及抗干扰改善因子模型,从而构建了箔条干扰条件下舰空导弹单发命中概率模型,计算出真实有效的单发命中概率.
