给出了一种可用于不等样本情况下的雷达与ＥＳＭ航迹的相关算法。该算法主要包括相关规则、多义性处理和决策门限的设置，并对算法进行了理论分析和仿真。 A correlation algorithm for radar and ESM trajectories is presented for unequal samples. The algorithm mainly includes the setting of relevant rules, polysemy processing and decision-making threshold, and carries out theoretical analysis and simulation of the algorithm.
