为了满足瞄准式战斗部定位攻击的需要，根据防空导弹逆轨拦截遭遇段只要存在脱靶量就存在视线角速度的特点，分析了导引头视线角、视线角速度、弹目相对速度、径向速度之间的几何关系，提出了采用导引头产生的视线角、视线角速度及多普勒频率来测量脱靶量的方法，解决了利用导引头距离信息测量脱靶量时误差较大的问题。对算法中需要的参数可测性进行了分析，通过导引头能否提供视线角速度信息两种情况下的仿真，验证了所提算法的正确性及实用性。

For the gimbaled warhead,attacking the target in a choosen position is quite necessary.Based on the character that miss distance will certainly lead to an angle velocity of the seeker in the encounter segment of an air defense missile when attacking the target in reversing track,the geometry relations of the sight angle, sight angle velocity,relative velocity between missile and target,and the radial velocity are analyzed.A method of miss distance measurement using the sight angle,sight angle velocity and Doppler frequency is advanced.The problem of appreciable error arising in the measurement using distance data is solved.At the same time,the measurability of parameters is analyzed,too.At last,with the simulations in two different situations that the seeker can give and cannot give sight angle velocity,the validity and utility of the method is proved.
