摘　　要：该文基于小波框架条件及多分辨率特性,提出了一种新的自适应航迹关联算法。将目标航迹数据序列分解为整体走势和局部特征两方面来解决航迹关联问题。当目标作匀速直线运动时,只比较两航迹的整体走势;当目标作机动运行时,同时比较两航迹的整体走势和局部特征(机动性)。理论分析和仿真实验证明了该算法的有效性和合理性。A new self-adaptive tracks correlation algorithm is proposed based on the wavelet frame condition and multi-resolution transform. The target track sequences can be decompounded to the whole trend and the detailed character of the tracks to solve tracks correlation problem. This algorithm may adapt well to the maneuvering and non-maneuvering targets tracks correlation. Furthermore, the theory analysis and simulation results show this algorithm is effective.
