For automatic recognition of radar pulse modulation mode, a simple and practical modulation recognition method was proposed. According to comparison of characteristics of the different pulse modulation signal, six different signals including conventional radar signal, BPSK signal, QPSK signal, FSK signal, LFM signal, NLFM signal can be quickly identified by measurement of the 3dB bandwidth, timedomain cumulative and time-frequency transform methods. Simulation results show that the method has a high identification probability. This method is verified to have effectiveness and practicality by implementation on the FPGA.
