Abstract :
The paper studies the recognition of BPSK and QPSK signal based on phase unwrapping and time-frequency curve analysis. First it proposed a phase unwrapping method, then get the time-frequency curve of radar signal and recognize the two phase-encoded signals through curve analysis, peak detection and amplitude comparison. At last, this method is simulated and analyzed. According to the simulation results, this method is effective.
