数字锁相环，采用costas环的数字形式，实现跟踪载波相位，(Digital phase-locked loop, using the digital form costas loop to achieve carrier phase tracking,)

SIFT特征匹配算法是目前国内外特征点匹配研究领域的热点与难点，其匹配能力较强，可以处理两幅图像之间发生的平移、旋转情况下的匹配问题(SIFT features matching algorithm is the hot matching algorithm of feature points at home and abroad . its matching ability is strong.It can match the feature points of two images which are rotated or traslation.)

模拟平面波和球面波发生代码，在后面可进行衍射干涉的各种模拟。(Simulation of a plane wave and spherical wave code behind a variety of simulated diffraction interference.)
