English Description：
The signal processing of pseudo phase coded CW radar is simulated. Let the code frequency be ﹥ 5MHz, the code length in the PN code period be 511, the radar carrier frequency be ﹥ 10GHz, the input noise be Gaussian white noise, the video input signal-to-noise ratio be - 15dB, and the total time width of coherent integration be no more than 0ms. The expressions of echo video, pulse pressure and FFT are given. The simulation results show that the pulse pressure and FFT are the same The simulation shows the relationship between the processing gain of each stage and the time width and bandwidth of each stage; the simulation shows the Doppler sensitivity phenomenon, Doppler tolerance and performance loss (the curve of pulse compression ratio and Doppler)
