基于Kalman滤波的机动目标跟踪方法研究

飞行器的机动性大,在运动过程中随时会出现转弯、跃升俯冲等现象。雷达跟踪系统能否对这种机动进行有效捕获,成为检验其可靠性的关键。在传统Kalman滤波方法基础上,对目标的运动状态进行检测,一旦检测到机动,滤波器就进行不同维数的转换,使跟踪结果快速收敛,从而实现对机动小目标的精确跟踪。仿真结果证明该方法正确有效,计算简便。

Research into Motive Target Tracking Method Based on Kalman Filtering

The maneuverability of aircraft is great,during its motion course,the phenomenon such as turn,leap and dive,etc.will appear at any moment.Whether the radar tracking system can effectively fetch the motion becomes the key to test its reliability.Based on the traditional Kalman filtering method,this article performs test to the movement state of target,if the motion is tested,the filter will perform the transform between different dimension in order that the tracking result convergences fast,thereby the accur...
