| Abstract: | The problem of how to analyze PSK modulation rules is discussed in the paper. How to get the rules of phase-shifting from the coherent integration of single pulse is first introduced, on the basis of which an approach to restoring PSK sequence is derived. In the paper , the method is improved by adopting multi-rank coherent integration of single pulse, so that it has good adaptability under Low-SNR condition, which is proved to be right according to some simulation results. |
