SLM_IG_simulation

code for show a ecography using beam forming

说明：  对心音信号实现平均周期图法功率谱估计的matlab程序(PSD bartlett matlab)

雷达天线————圆形阵列边界的矩形网格天线增益方向图( a rectangular grid array antenna gain pattern of Circular boundary )

信号分析功能说明,图表，波形，二进制，十六进制，浮点(signal analysis discrape)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标加速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)

说明：  信号检测与估计理论的一本好书，这方面的原版书籍不是很多，这是比较清晰而且可以借鉴的一本(Signal detection and estimation theory of a good book, this is not a lot of original books, it is more clear and can draw on a)

一个用来进行频谱分析的程序，可以根据记录的信号序列的富氏变换来求得本征频率值(used for a spectrum analysis procedures, can record the signal sequence of Fourier transform to obtain the frequency of levy)

matlab 匹配追踪算法,garbor原子的，非常好用(matlab matching pursuit)

模式识别中关于特征选择和特征提取的知识。。。(Pattern recognition on feature selection and feature extraction of knowledge. . .)

基于fdtd算法利用matlab软件编写的计算问题空间的程序，适合光电子和晶体等领域(Based on FDTD algorithm using matlab software to write the calculation problem of the space program, suitable for optoelectronic and crystal, etc)
