Specific radar emitter signal sorting and recognition is the critical segment of signal process- ing from complex signal environment. With the foregone information of minatory complex signals, the principle of time series comparability in data mining field and the technique of slip window are intro- duced. So a new method of fast matching for the pulse changes of several parameters radar signal is given. With the experiments, it is showed that this method has quick recognition speed, powerful adapted environment ability and a good application foreground.
