摘　　要：以相对运动方程组为基础，分析了导引律的运动学实质和过重力补偿的信号流图，进而分别对比例导引和基于过重力补偿为常值的过重力补偿比例导引下的弹道进行了对比仿真计算。结果表明，过重力补偿比例导引适用于攻击非机动和机动性不大的目标，落角增大，命中点附近视线偏转和控制过载变大，能够实现对目标的大落角攻顶效应。Based on the relative movement equation group, the essence of kinetics and signal flow of over -gravity compensation are analyzed. The trajectories of proportional navigation and trajectories of overgravity compensation are calculated for comparative simulation. The results indicate that proportional navigation with over-gravity compensation is suitable for attacking fixed or less mobile targets, and especially for hitting the top of the target, for its angle of fall is greater and the line of sight at the point of impact has deflection and greater overload.
