| Abstract: | Several performance indexes of the P4 polyphase codes such as the ambiguity function and the accumulative sidelobe level are briefly introduced.The Doppler performances of the P4 polyphase codes after the sidelobe suppression through applying the sampling and sliding window are analyzed in detail,and the changes of both the amplitude of main peak and the PSLR with the Doppler shift after the pulse compression are given through the MATLAB simulation,which indicates that the method of the sampling and sliding window is effective in sidelobe suppression and provides a theory basis for engineering applications. |
