摘　　要：激光半主动末制导炮弹能实现对目标的"攻顶"效应,分析了"攻顶"技术及其理论实质,即过重力补偿比例导引律的应用,以弹丸和目标的相对运动方程为基础,通过M atlab仿真计算的方法,分析了比例导引系数、弹丸与目标的速度比、过重力补偿值等主要参数的变化对弹道性能的影响,提出了导引律实现中注意的几个问题及改进制导系统的建议.Laser Semi-active Terminal Homing Projectile can actualize attack on the top of the target. It is analyzed that the technique of top-attack and its theoretical matter is the application of the Proportional Navigation with Compensation over Gravity. Based on the relative movement equation group of the projectile and the target, using Matlab to make the simulation and calculation, it is analyzed that the affection of the major parameter＇ change to the trajectory, such as proportional navigation quotiety, the velocity ratio of projectile and target, the compensation over gravity, and so on. Some problems in the actualization of guidance and some suggestion on the improvement of the guidance and control system are offered in the paper.
