The automatic radar impulse character recognizable algorithm is presented in this paper.Its variance of nonlinear phase,statistical histograms of IF(Instant Frequency),variance of IF and resemblance coefficient are extracted based on different characteristics of radar illuminator signals,which then are combined together to classify the common modulation,such as CW signal,LFM signal,NLFM signal,FSK signal and PSK signal.Simulation result shows it is effective even with a low signal-to-noise ratio.
