Firstly several feature parameters for signal recognition are extracted with Welch power spectrum,then a signal recognition model is designed by the characteristic of the feature parameters. Liner frequency modulating signal, phase coded and frequency coded signal are detected and recognized from all kinds of signals. The suitable range and signal＇s condition of the feature parameters are analyzed. Simulation proves the feasibility of the algorithm and the recognition method.
