复合制导空空导弹截获目标概率研究

中远程空空导弹普遍采用中制导加末制导的复合制导体制,在中末制导交接段,导弹截获目标的概率(TAP)是一个重要的设计指标。建立了一种工程上实用的截获概率计算数学模型,研究了影响截获概率的5种主要误差源及其计算公式,并给出了一条典型弹道的截获概率计算结果。该方法特别适用于研究不同误差源对截获概率的影响,可以在一次弹道计算中得到该条弹道的截获概率。

Study on Target Acquisition Probability of Air-to-air Missiles with Combined Guidance

Medium/long range air-to-air missiles usually adopt a combined guidance of midcourse and terminal. The target acquisition probability (TAP) for a missile in the takeover stage from midcourse to terminal phase is a key design parameter. In this article, a practical mathematical model for calculation of the target acquisition probability is built up, five main error sources which may have an impact on the TAP and their calculating formulas are studied, and the TAP calculation result for a typical missile trajectory is given. This method, by which the TAP can be obtained from a single trajectory calculation, is especially suitable to estimate impacts of various error sources on the TAP.
