JPEG编码的MATLAB程序代码，条例清晰，方便好用(JPEG encoding MATLAB code, regulations clear and is easy to use)

matlab数字水印程序m文件程序，用的是小波变换中的dwt方法，并且把小波变换分成了四个子带，选择的LL子带。svd算法与dwt相结合，加密方法是混沌加密。与我刚才上传的dwt_svd_GUI.rar是一个程序，一个是gui的，一个是m文件。(m digital watermarking matlab program documentation procedures, using a wavelet transform method in the dwt and the wavelet transform is divided into four sub-band, choose the LL sub-band. svd algorithm with a combination of dwt, encryption method is chaotic encryption. I have just uploaded a dwt_svd_GUI.rar procedures, one is the gui, one m file.)

最小方差无失真响应，波束形成，增强信号。(Minimum Variance Distortionless Response ,Digital Beamforming,Siginal Enhancement)

对matlab的基础知识进行介绍，对入门学习matlab很有帮助(Introduces the basics of matlab matlab helpful for beginners learning)

基于均匀圆阵的信号二维方向角高精度估计 (Angular precision estimates based on two-dimensional uniform circular array signal direction)

合成孔径雷达成像的三个经典算法matlab仿真。包括RD算法，Chirp Scaling算法，wK算法。程序正确，注释清晰。(Synthetic aperture radar imaging of three classical algorithm matlab simulation. Including RD algorithms, Chirp Scaling Algorithm, wK algorithm. Program correctly, clear notes.)

说明：  对于受轴向力的板结构，求取单元应力，节点位移，和固有频率(For the plate under axial force to strike element stress, node displacement, and natural frequency)

本程序利用球形不变随机过程法模拟产生服从瑞丽分布的海杂波，适合实验室环境下做为海杂波的输入信号。(The program uses the same random process simulation of spherical produce the distribution of sea clutter obey Ruili, suitable for sea clutter under laboratory conditions as the input signal.)

说明：  使用matlab，spa算法提取光谱的特征波长，结合了plsr(Using MATLAB and Spa algorithm to extract the characteristic wavelength of the spectrum, combined with PLSR)
