摘　　要：脱靶量是检验寻的飞行器性能的一项重要指标,为了提高脱靶量解析计算精度,应用理论推导,建立了控制作用下的脱靶量解析计算模型,分析了影响脱靶量的参数,并通过数字仿真,研究了脱靶量变化规律。结果表明:所建立的脱靶量解析计算模型正确,相比传统零效脱靶解析计算模型具有更高的解析计算精度,在众多影响参数中导引头盲区大小、稳定系统响应快慢、目标横向机动能力是影响终端脱靶量的关键因素,最后给出了减小终端脱靶量的措施。Miss distance is an important index to test the performance of homing vehicle.In order to improve the accuracy of analytical calculation for miss distance,an analytical calculation model of miss distance under control is established by theoretical derivation.The parameters affecting miss distance are analyzed,and the variation rule of miss distance is studied by digital simulation.The results show that the analytical calculation model of miss distance established is correct and has higher analytical calculation accuracy than the traditional analytical calculation accuracy model of zero-effort miss distance(ZEM).Among the influence parameters,the seeker blind distance,the response time of control system,and the target maneuverability are the key parameters.Finally,the measures to reduce the miss distance are given.
