摘　　要：介绍了弹体追踪制导律的特点,通过对弹体纵向运动的动力学方程线性化处理,推导出脉冲力控制的弹体传递函数,分析了脉冲力大小对脱靶量的影响。给出探测器捷联体制下的脉冲力控制算法,并对该控制算法进行仿真。分析了脉冲力作用位置对制导精度的影响,提出采用脉冲力提供重力补偿可以提高弹丸命中精度的方法。The characteristic of body pursuit guidance was introduced. The transfer function of impulse force control was deduced according to the linearization of longitudinal kinetic equations, and the relationship between the different value of impulse force and the miss distance was analyzed. The control algorithm of the impulse force control was designed and simulated based on strapdown laser detector. The affection of the hit precision with different positions of impulse force was analyzed. The simulation results show that the hit precision can be improved greatly by using the gravity compensation with impulse force.
