摘　　要：针对现有船舶导航雷达目标跟踪处理中难以妥善解决的误跟踪问题，提出雷达相关跟踪检测新方法．文中采用小波分解提取目标运动特征信息，用局部Ｌｉｐｓｃｈｉｔｚ指数作为波门有重叠的交叉目标数据分离的依据，并且推导出在线快速ＷＴ分解公式以提高数据处理的实时性．This paper presents a novel method for extracting the characteristics of moving target by means of wavelet decomposition to correlatingly detect the mistracking in marine radar track. The local Lipschitz exponent is employed to separate the data of two targets that fall into the same gate. In order to process the data realtimely, the fast wavelet transform on line algorithm is derived in this paper.
