Coherence can be used as a characteristic parameter of radar signal sorting,which can effectively avoid the occurrence of"missing batch".Based on the principle of correlation recep-tion,the influence of different initial phase difference on the output signal waveform after correla-tion reception is analyzed.By deducing the expression of the waveform of the main peak of the output signal,a coherent characteristic model of radar pulse signal is established,and the process of signal sorting is also given.The simulation results show that the model is suitable for complex pulse aliasing,and still has a certain sorting accuracy when the signal-to-noise ratio is-5 dB and the initial phase difference is 0.2 rad.
