寻的防空导弹的一种弹道优化方法

为保证雷达寻的防空导弹遇到目标时脱靶量最小,分析了影响导弹视线角速度诸因素,以命中时导弹需用过载最小为条件,得到了纵向加速度和重力2项优化因子,以补偿它们带来的视线转率和弹道弯曲,实现了比例导引规律的弹道优化.仿真表明该方法对高空、高远弹道的改善效果明显,弹道变得较为平直.该方法在工程上易于实现.

A Method of Trajectory Optimization for Homing Antiaircraft Missile

To ensure the minimum miss quantity when the radar homing antiaircraft missile encounters target,elements affecting the line of sight(LOS) angular velocity of the missile were analyzed.Two optimization factors including longitudinal acceleration and gravity were obtained by using the conditions of minimum required overload while missile hitting,which could compensate the LOS rotation rate and trajectory curvature.The trajectory optimization by proportional guidance was accomplished.The simulation results show that the method has a significant improvement for the high-altitude and long-distance trajectory.The trajectory become straight.This optimization method is easily realized in engineering.
