【摘要】 弹目遭遇末端目标至脱靶点剩余飞行时间的估算对起爆控制来说是非常重要的。本文详细讨论了脱靶情况下距离未知或丢失时 ,如何利用导引头测得的角度和角速度信息预测剩余飞行时间以及其它参数。结果表明对于非机动目标 ,文中方法估计的剩余飞行时间及其它参数没有误差 ;目标机动能力的增加会导致预测误差变大 ,但是随着导弹逐渐接近目标以及剩余飞行时间的减小 ,预测精度也会逐渐提高。考虑到允许的起爆延时误差 ,目标机动对剩余飞行时间估计的影响是很小的更多还原

【Abstract】 During the missile target terminal encounter,the predict of time to go until miss point is of great significance to burst control.Generally,the image seeker or radio seeker can provide the angle and angular velocity information,how to utilize these information to predict the time to go and other parameters under miss case when the range is not know or is lost was discussed in detail.The result shows that for nonmaneuvering target case,predicted time to go and other parameters has no errors;the predict errors will become larger with the increase of target maneuvering acceleration,but the accuracy will be improved with the missile approaching the target and the decrease of time to go.considering the burst time delay error allowed,the effect of the target maneuver is very small to the predict of time to go.更多还原
