摘　　要：针对被动寻的式侵彻炸弹的特点,设计了具有末端落角约束的变结构制导律,并采用将制导指令经过一阶低通滤波器的方法,实现对弹体攻角的估计。将该制导律用于电视制导侵彻炸弹的数学仿真,通过仿真讨论了制导律参数对制导效果的影响。仿真结果表明,该攻角估计方法是可行的,该制导律能够同时满足脱靶量和末端落角的要求,达到侵彻炸弹控制弹着角的目的。According to the characteristics of passive homing penetrating bomb, the variable-structure guidance law with terminal angular constraint is designed. The bomb＇s angle-of-attack is estimated by the method that the guidance command passes through a first order filter. The guidance law is used for the simulation of a video-guided penetrating bomb. And through the simulation, the influence of the guidance law parameters on the guidance performance is discussed. The simulation shows that the angle-of attack estimation method is feasible, and that the guidance law can meet the demands for both terminal miss distance and impact angle.
