| 摘 要： | 在只有视线角速度信息的情况下,为了寻找即保证目标可观又保证命中精度的弹道,通过分析弹目相对运动系统状态方程的可观性矩阵的迹,理论推导了影响目标可观性的因素.运用根据变结构理论设计的新型非线性制导律进行了仿真,结果表明命中精度良好,可观性矩阵的迹是弹目速度夹角的增函数、弹目相对速度绝对值的增函数、剩余飞行时间的增函数和弹...

| Abstract: | In order to attain the trajectory which guarantees not only good target observability but also better hitting accuracy based on line-of-sight(LOS)angle rate,the factors affecting target observability were deduced theoretically by analyzing the trace of observability matrix corresponding to the state equation of a missile-target relative motion system.A nonlinear guidance law designed by variable structure control theory was applied to carry out simulation.Simulation results show that hitting accuracy is bet... |
