A Novel Method for Sorting Unknown Radar Emitter

A new method based on the second dimension of resemblance coefficient (Cr2 ) and the fourth dimension of wavelet packet transform (Wpt4) to improve the sorting correct rate of unknown radar emitter is presented in this paper. The Cr2 and Wpt4 is extracted firstly and used as the sorting basis when the unknown radar emitter signal is received, then the radar emitter sorting can be realized by the fuzzy c-means algorithm based on kernel(KFCM). Simulation result shows that the new method can get higher correct rate than traditional method.
