介绍关于MATLAB的一些函数基本命令以及常用的处理图像方法(Introduced the MATLAB function basic commands as well as the commonly used image processing method)

三个基于延时的波束形成程序，在声纳、雷达等领域有广泛应用，能正常运行，都有仿真图，推荐下载(Three delay-based beamforming codes,have wide applied in sonar, radar and other areas,all of them have the simulation graph, it is recommended to download)

脉冲多普勒雷达是利用运动的物体对发射信号的产生的多普勒效应来测速和测距的，利用回波的延时可以测距，求出多普勒频率可以求出物体的速度(Pulse Doppler radar is to use the Doppler effect on the motion of an object generated by the transmission signal to the speed and distance, the distance can use the echo delay, the Doppler frequency can be calculated the speed of the object is obtained)

最基础的检测概率；虚警概率；漏检概率与门限的关系。(Energy detection;Single threshold.)

广义奇异值分解程序，常应用于数据处理，例如信号处理(The generalized singular value decomposition (GSVD) is a matrix decomposition more general than the singular value decomposition. It is used to study the conditioning and regularization of linear systems with respect to quadratic semi-norms.)

供做算法研究人员参考，包括回归分析和概率统计，FMCW调频连续波雷达的测距测角，用平面波展开法计算二维声子晶体带隙,ldpc码的编解码实现，连续相位调制信号(CPM)产生。
