A New Method of Unknown Radar Signals Sorting Based on Clustering
Jie Dai · Electronic Information Warfare Technology · 2012
The k-means clustering algorithm is considered that it is not applicable to unknown radar signal sorting.A sorting method based on improved grid clustering is proposed.Signal grid and noise grid are distinguished using the double-density threshold,after data points are mappinged to grid space.Finally,the signal sorting is achieved through the high density connectivity of grids.In addition,the signal sorting without any prior knowledge could be accomplished,and this method is unsensitive to the noise.The simulation results validate the effectiveness of the method.
