中文摘要：
提出一种基于多传感器航迹的关联算法。首先根据雷达和目标球极投影后的几何位置关系，利用三角形的几何性质分别建立两个航迹关联函数，并利用加权思想进一步建立相似度函数；在此基础上，利用一阶泰勒展式对航迹关联函数理论分析获得航迹粗关联门限；然后依次通过粗关联和精关联实现航迹关联。仿真结果表明了该算法的时效性和稳定性。
英文摘要：
This paper proposes a novel track correlation algorithm in multi-sensor system. Firstly, two tracking correlation function are constructed according to geometry relation between radars and targets and also the geometry properties, and the similarity function is set up by weighting idea. Based on this, tracking coarse correlation threshold is obtained based on theory analysis on tracking correlation by using Taylor series expansion. Then tracking correlation is finished through tracking coarse correlation and fine correlation. Simulation verifies the proposed algorithm on time consumption and stahility.
