摘要

The sorting of radar emitter signal is a very important part of electronic countermeasures. With the rapid development of electronic techniques, radar signal becomes more and more complicated, and the sorting of signal becomes more and more difficult. Under this environment, new sorting methods must be proposed and applied. This paper summarizes the significance, the system composition and the sorting flow of radar emitter signal sorting firstly. Then, it introduces the improved K-means algorithm. For the sake of achieving signal sorting availably, an improved K-means algorithm for signal sorting is proposed. This method can sort direction of arrival, radio frequency and pulse width parameters. Finally, this paper introduces the simulation experiments. Experiments results show that this method is easy, and it is effective in sorting radar emitter signals.%　　雷达辐射源信号分选是电子对抗领域一个关键技术，随着电子技术的发展，电磁环境日趋复杂，信号分选的难度越来越大，在这样的条件下，我们应该寻求新的解决问题的方法。本文首先概述了雷达辐射源信号分选意义、系统组成和分选流程，然后介绍了改进 K-均值算法。为了有效实现信号分选，提出了基于改进K-均值算法的信号分选方法，该方法可对到达角、载频和脉宽参数进行分选。最后进行了仿真实验，结果表明该方法实现简单，分选效果较好
