Based on the ambiguity function, an approach to intra-pulse modulation recognition is presented. This paper defines the frequency energy accumulation FEAF) and time-domain extremum TEF) to describe the Doppler frequency shift and time delay properties of signals, respectively. This approach can recognize six types of signals by four characteristic parameters. Simulation results show that the probability of successful recognition (PSR) can reach 90% when the signal to noise ratio (SNR) is above -1 dB.
