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。
Medium and long-range air-to-air missiles are generally used in the system of guidance and guidance of the composite guidance system, at the end of the guidance of the transfer section, the missile interception target probability (TAP) is an important design indicator. An engineering mathematical model of interception probability calculation was established. Five main error sources and their calculation formulas that affected the interception probability were studied. The calculation results of the interception probability of a typical trajectory were also given. The method is especially suitable for studying the influence of different error sources on the probability of interception, and the probability of interception can be obtained in a ballistic calculation.
