中文说明： 本代码基于雷达信号处理基本原理在工程上的应用，首先给出了LFM信号的模糊函数，以及等高线图，并计算了时间模糊函数和多普勒模糊函数，并给出了模糊函数6db等高线图，并计算了距离和多普勒频率与时间的关系，通过产生现行调频信号，并对现行调频信号进行了匹配滤波处理和加窗的线性调频信号匹配滤波，在进行相干积累之后，进行了脉冲压缩，之后进行了目标多普勒通道的CFAR处理信号，最后给出了目标回波相干积累前、后的信噪比SNR与距离的关系曲线。该代码对于从事雷达信号处理工程实现上具有一定的借鉴意义
English Description：
This code based on radar signal processing principle in engineering Shang of application, first to out has LFM signal of fuzzy function, and contour figure, and calculation has time fuzzy function and more general Le fuzzy function, and to out has fuzzy function 6dB, high line figure, and calculation has distance and more general Le frequency and time of relationship, through produced existing FM signal, and on existing FM signal for has match filter processing and added window of linear FM signal match filter, in for coherent accumulated zhihou, for has pulse compression, After the CFAR target Doppler Channel signal processing echoes coherent was given before and after the signal to noise ratio SNR and distance curve. The code for radar signal processing engineering has some significance
