为解决雷达与ESM航迹关联门限的不确定性，提出了基于几何法的雷达与ESM航迹关联算法。该算法根据雷达与ESM的几何位置建立航迹粗关联函数，并利用航迹的历史信息建立航迹关联代价矩阵，通过代价最小实现航迹关联。仿真结果表明，该算法具有很好的关联性能。

In order to deal with the uncertainty thresholds of Radar-ESM (Electronic Support Measures) correlation,an Radar-ESM correlation mode based on geometric method was proposed.Firstly,a coarse correlation function was built up based on the geometric position of radar and ESM.Then,a cost correlation matrix was set up by accumulating the historical information of the coarse correlation.Thus the track correlation was realized by finding the minimum cost of cost matrix.Finally,the correlation method proposed was verified by Monte Carlo simulation.
