摘要
在现代战争中随着新体制雷达的不断涌现,电磁环境变得越来越复杂,这就对雷达信号分选提出了新的挑战。目前普遍采用的基于直方图统计的信号分选方法越来越不适应现代雷达信号环境。文中将聚类分析技术引入到雷达信号分选中,将蚁群算法和K-Means相结合,互相弥补不足,提出了一种新的雷达信号分选方法,该方法易编程实现,不需要雷达信号的先验知识,适用于处理未知信号的雷达。仿真实验证明分选结果较理想,为雷达信号分选提供了新的思路。
As advanced radars increase rapidly in modern warfare, electromagnetic environment becomes more and more complicated, and radar signal sorting faces new challenge. Signal sorting methods adopted at present based on statistic histogram don＇t adapt modern radar signal environment more and more. In this pa- per, clustering analysis is introduced into radar signal sorting. Ant colony algorithm and K-Means are com- bined. A new radar signal sorting method is presented. This method is easy to realize by programming and does not need priori knowledge of the radar signal. It is suitable for dealing with the unknown radar signal. The simulation shows that the method has good sorting result, providing a new way for radar signal sorting.
