Xuesong Wu · Avionics Technology · 2012
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.
