Recognition of low probability of interception (LPI) radar signals is extremely important in electronic support measurement (ESM), or electronics intelligence (ELINT) systems. Polyphase codes including Frank, P1, P2, P3, and P4 code are a kind of LPI signals, which have been a new research hotspot in reconnaissance systems. In this paper, we propose a new recognition method for polyphase coded signals using the time-frequency rate (TFR) distribution. First we use the property of linear… CONTINUE READING
