Abstract
PCM (phase-coded modulation) signal is a kind of radar signal that is widely used in many circumstances, such as PD processing, communication, etc. In wild electromagnetic environment, the identification of PCM signals is important in passive location system. STFT is an efficient method in time-frequency analysis, which can exactly identify PCM signals with wave-entropy analysis. Theory verification and simulations have proved the method to be correct and practical.
