The automatic analysis of intrapulse modulation characte- ristics based on the relatively non-ambiguity phase restoral

HUANG Zhi-tao, ZHOU Yi-yu, JIANG Wen-li ( School of Electronic Science and Engineering, NUDT, Changsha 410073, China)  
The problem of how to automatically analyze intrapulse modulation characteristics is discussed in the paper. An approach to restoring relatively non-ambiguity phase is first introduced, which is proved to be effective according to some simulation results. And the modulation recognition methods for BPSK and QPSK based on the amplitudes of peaks of the phase difference and for LFM based on LS fitting of a line are developed. The critical signal-to-noise required to effectively identify the modulation is also discussed. Several simulations are performed on BPSK, QPSK and LFM, and simulation results demonstrate the efficiency of the modulation recognition approaches.
