Study on the Simulation of the Maneuvering Target Tracking Based on Proportion Guide

针对比例导引目标的跟踪问题,将比例导引规律引入状态方程,建立线性时变系统模型,利用含有参数的标准卡尔曼滤波方法给出了目标的状态估计。运用语言进行仿真计算,分析并得到了在不同的初始航向角、比例导引系数、导弹的初始位置和速度下的导引弹道滤波曲线和弹目相遇时间。仿真结果表明,此方法正确可行。

Concerning the problem of maneuvering target tracking, the character of proportion guide is introduced into state equation to construct a linear time-varying system model, and the state estimate of the system can be obtained using the standard kalman filter with parameters. Then the Matlab language is used to simulate it, and different guide trajectory filter curves and encountering times of missile and target are obtained by analyzing various conditions of different initial values of voyage direction, prop...
