跟踪飞机机动的自适应滤波方法

本文研究了对目标机动的最优检测问题,针对飞机主要有三种飞行状态:匀速直线运动、加速直线运动与圆运动这一特点,提出了既探测飞机机动又同时判断飞机作何种形式的机动的方法;并建议对飞机的不同飞行状态,采用相应的动态模型。在此基础上,给出了自适应滤波方法。最后给出的仿真计算果表明,自适应滤波方法有较高的跟踪精度。

A ADAPTIVE FILTER FOR TRACKING THE MANEUVERING TARGET Institute of Systems Science. Academia Sinica

The tracking problem for the maneuvering target is studied and an adaptive filter is shown in the paper. In the adaptive filter we adopt the different dynamical models depending on the flight states of the airplane and present the optimal detecting method which not only detects maneuver of The airplane but also determines the fashion of the maneuver based on the three typical 'light states of the airplane; the straight line motion with constant speed, the straight line maneuver with constant-acceleration and the turn maneuver. The simulation examples show that the adaptive filter provides the higher tracking accuracy.
