目前多通道SAR成像比较热门，这个程序就是实现MIMOSAR成像的程序，供学习！(More popular multi-channel SAR imaging, this program is achieve MIMOSAR imaging procedures for learning!)

相参脉冲串复调制信号，仿真图是速度、距离、幅度三维图像，是小学期课程设计的题目。( Complex modulation coherent pulse train signal, FIG simulation speed, distance, amplitude three-dimensional image, Is the topic of the elementary school stage curriculum design.)

现代通信越来越依靠全数字处理技术, 通信系统中的全数字调制解调意味着发射机 及接收机将全部采用数字信号处理(DSP) 算法, 从而整个通信系统就可以用DSP 芯片或超 大规模集成电路(VL S I) 器件来实现。对全数字BPSK 调制解调系统采用计算机仿真的方法 进行研究能清楚地了解通信系统中所运用的数字信号处理技术, 包括信息源、发送和接收 滤波器、内插器以及判决器等全部采用数字信号处理算法来实现。文章给出了BPSK 调制 解调系统各个模块的算法和结构, 运用MA TLAB 软件进行了仿真, 得出了各个部分的时域 和频域波形图, 系统仿真的设计方法对Q PSK、16QAM 等全数字调制解调系统的硬件实现 具有实际的指导意义。()

16QAM软解调方式，适合与Turbo码、LDPC等结合，可按照次思路扩展到高阶调制和解调(16QAM soft demodulation method, suitable combination of Turbo codes, LDPC, in accordance with sub-ideas to be extended to higher order modulation and demodulation)

说明：  通信信号相干调制解调源码 Fc=10 ％载频 Fs=40 ％系统采样频率 Fd=1 ％码速率 N=Fs/Fd df=10 numSymb=25 ％进行仿真的信息代码个数 M=2 ％进制数(Coherent modulation and demodulation of communication signal source Fc = 10 carrier frequency Fs = 40 systematic sampling frequency Fd = 1 code rate N = Fs/Fd df = 10 numSymb = 25 of the information code to simulate the number of M = 2 hexadecimal number)

说明：  This is a matlab code and is a beneficial source code

克里格法是地统计学的主要内容之一，从统计意义上说，是从变量相关性和变异性出发，在有限区域内对区域化变量的取值进行无偏、最优估计的一种方法；从插值角度讲是对空间分布的数据求线性最优、无偏内插估计一种方法。(Kriging method is one of the main contents of geostatistics. Statistically speaking, it is a method of unbiased and optimal estimation of regionalized variables in a limited area from the point of view of correlation and variation of variables; from the point of view of interpolation, it is a method of seeking linear optimum and unbiased interpolation estimation of spatial distribution data.
