基于改进的半监督AP聚类雷达信号分选
Radar signal sorting based on improved semi-supervised affinity propagation clustering
摘要
Abstract
Radar signal sorting is a crucial aspect in modern high-tech warfare and information warfare,and is also an im-portant part of electronic warfare. In the perspective of time-frequency analysis,the signals of different modulation modes have different decomposition coefficients in some bands,and these differences allow the features extracted by the wavelet packet to recognize the modulation modes of signals. The cluster analysis of the statistical characteristics of signal wavelet packet energy entropy is performed by the improved semi-supervised affinity propagation clustering algorithm. Compared with other two algo-rithms,the improved semi-supervised affinity propagation algorithm is more effective and its accuracy is higher. In addition,the number of clustering is closer to the actual number.关键词
