雷达采用匹配滤波完成脉冲压缩，采集频率fs=420MHz,仿真雷达回波，并绘出加Hamming窗前后的脉压波形。目标如图所示由(-5，-2)，(0，5)和(6,-7)三个散射点组成,散射强度分别为（1，2，5）,雷达位于（-5000,0）处(The completion of the radar pulse compression using matched filtering, collecting the frequency fs = 420MHz, simulation of the radar echo, and draw the Hamming window plus post-pulse pressure waveform. Targets as shown by (-5,-2), (0,5) and (6,-7) three scattering dots, scattering intensity, respectively (1,2,5), radar at (-5,000, 0), Office of)

此程序为混有高斯白噪声的多径信道下的仿真，参数根据需要可以再次优化(This procedure mixed with white Gaussian noise multipath channel simulation, the parameters required can be re-optimized)
