说明：  这是matlab编写的射线网格法追踪，用于追踪波的射线轨迹(This is prepared matlab ray tracing grid method, used to track wave ray tracing)

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections.

实现二维正向正态云发生器 ，非常好用 (2D forward the normal cloud generator)

通过固定波束形成算法进行语音增强的一个仿真程序，这个算法是麦克风阵列语音增强里最基本的，值得研究。(Formed by a fixed beam speech enhancement algorithm, a simulation program, this algorithm is the microphone array speech enhancement in the most basic, is worth studying.)

说明：  进行带钢厚度预测，通过提取带钢厚度的特征，输入svr进行预测。(Prediction of strip thickness)

32个脉冲调制的线性调频连续波发射信号，单目标回波信号中加入了距离时延与多普勒频移信息。数字下变频后再进行脉压与MTD处理从而检测出距离与速度信息。(Chirp 32 pulse-modulated continuous wave transmit signals, a single target echo signal from the delay and added to the Doppler shift information. MTD frequency pulse pressure and then be processed to detect the distance and speed of digital information down.)
