本文研究了使用子波变换进行目标跟踪的方法，采用对原始测量进行多分辨分解和对目标运动模型进行多分辨分解的方法实现了在信噪比较低的情况下对目标的弱机动进行提取。
In this paper, the method of target tracking using wavelet transform is studied. By using multi-resolution decomposition of the original measurement and multiresolution decomposition of the target motion model, the weak motor can be extracted under low signal-noise ratio .
