摘要
提出一种小体积、低价格、结构紧凑的非扫描半导体激光主动成像制导技术,该技术能够实时获得目标的二维强度图象和弹目相对距离信息。以最优控制理论和飞行力学原理为基础,从考虑弹目相对速度变化方面入手,推导出一种变系数最优导引律,并给出剩余飞行时间的估算方法。数字仿真结果表明:最优导引律与经典比例导引律相比具有控制能量少,脱靶量小等优点。
A small,cheap and compact scannerless laser active imaging guided technology was proposed which can acquire the 2-D intensive imaging of targets on the ground and the relative distance between missiles and targets timely.Based on optimal control theory and aviation mechanics,the optimal guided law was deduced from taking the relative velocity into account,and the calculating methods of timeto-go were sented.The results of numeric simulation indicate that optimal guidance law has the smaller controlled energy and the shorter miss distance compared with classical proportional navigation.
