Intra-pulse Feature Analysis and Recognition of Phase-coded Signal

The problems of how to automatically analyze intrapulse modulation characteristics are 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 phase-coded based on the amplitudes of peaks of the phase difference are developed.Simulation results demonstrate the efficiency of modulation recognition approaches,and it gives the realization in the electronic countermeasures.
