English Description：
Signal processing of pseudo-random phase coded pulse radar. Let the code frequency be 02, in MHz, the code length be 127, the duty cycle be 10%, the radar carrier frequency be 10GHz, and the input noise be Gaussian white noise. The target simulation can be divided into single target and double target. The input signal-to-noise ratio of target echo is variable (- 35db-10db), the target velocity is variable (0-1000mgs), the target amplitude is variable (1-100), the target distance is variable (0-10000m), and the total time width of coherent integration is not more than 10ms. In the case of single target, the expression of echo video is given; the expression after pulse compression and FFT is given; the double level cyclic autocorrelation function of m sequence is simulated, and the output graph after pulse compression and FFT is given; the relationship between pulse compression output and FFT output is explained by simulation SNR, time width and bandwidth; simulation shows Doppler sensitivity, Doppler tolerance and performance loss (the curve between the peak value of main lobe and Doppler). In the case of double targets, the side lobe of large target is simulated to cover small target, and the range resolution and velocity resolution are simulated.
