机动飞行器的效能影响因素分析

针对防御系统目标跟踪和轨迹预报的原理，分析目标机动参数对估计误差和预报误差的影响因素，以及预报误差对拦截飞行器脱靶量的影响。以脱靶量为指标，分析目标机动的效能。研究结果表明，增加机动加速度大小、增加机动持续时间、选择合适的机动开始时刻可以增加估计误差与预报误差，从而增加脱靶量，提高目标机动的效能。

Effectiveness Affecting Factors Analysis of Maneuvering Flight Vehicle

According to principle of target tracking and trajectory predicting, the affecting factors of maneuvering parameters on estimation and prediction errors are analyzed, so is the influence of prediction error on intercepting miss distance. The miss distance is chosen to be the standard to analyze the effectiveness of target maneuvering. Research results demonstrate that increasing maneuvering acceleration, increasing persisting time, choosing appropriate start time will increase estimation error and prediction error, as well as increasing miss distance, so as to improve effectiveness of target maneuvering.
