拦截弹导引头测量误差对拦截效能的影响

摘要

把拦截弹导引头的测量系统作为拦截系统的一个子系统,从脱靶量及消耗能量两个方面,研究导引头测量误差在整个拦截系统中对拦截效能的影响.建立以拦截弹测量误差为激励,脱靶量及消耗能量为输出的比例导引拦截系统模型,对测量误差导致的脱靶量及消耗能量进行仿真,并通过数值统计得出拦截弹导引头测量误差与脱靶量及消耗拦截能量的量化对应关系,为拦截弹导引系统设计、导弹突防等提供技术参考.%Taking the intercepting missile seeker's measurement system as a subsystem of interception systems and focusing on miss distance and interception energy cost, the effect of interception seeker measurement error on interception efficiency is investigated. A proportional navigation interception system model is set up. In this system, input is an intercepting missile measurement error and outputs are miss distance and interception energy. Both the miss distance and the energy cost caused by seeker's measurement error are simulated in this system. By numerical statistics, the quantized relationships between the interceptor seeker's measurement error, the miss distance and energy cost are exhibited that provides technology reference to guidance system design or missile penetration for the intercepting missile.
