摘　　要：雷达辐射源分选是电子战系统的关键技术之一。为了解决传统基于五大参数方法不能有效分选高密度复杂雷达信号的问题,提出一种将表征信号脉内特征的相像系数作为分选参数投影到网格空间中以实现聚类的雷达信号分选新方法。新方法能够有效分选信号参数严重交叠的复杂雷达信号,在信噪比较低的情况下仍具有较高的分选准确率。模拟仿真验证了算法的有效性。Sorting of radar emitters is a vital technology of the radar countermeasure system. To solve the problem that complex radar signals cannot be sorted by the traditional methods based on five parame- ters, a new algorithm which adopts resembling coefficient for grid clustering is introduced. The approach can effectively sort complex radar signals, whose parameters are overlapped seriously. Even in noisy envi- ronment it can get appropriate accuracy of sorting. Extensive Monte Carlo simulation results indicate the effectiveness of the algorithm.
