理想阵列天线的仿真，参数具有可调性。对学习阵列雷达有很好的帮助(The ideal of the antenna array simulation, parameters is tonal. To study the array radar have very good help )

本算法结合小波变换和SVD奇异值变换，实现了水印的嵌入和提取，载体图像的鲁棒性和水印的不可见性，提取出的水印图像的和原水印图像基本一致，抗攻击性强。(The algorithm combines wavelet transform and SVD singular value transformation, achieved watermark embedding and extraction, vector image watermark robustness and invisibility, the extracted watermark image and the original watermark image are basically the same, anti-attack and strong.)

用MATLAB编写的TLS-ESPRIT算法，算法原理可参考张贤达版的现代信号处理，绝对可运行，程序配合书非常容易理解，而且稍微改改就可以变为基本的ESPRIT算法。(Written by MATLAB TLS-ESPRIT algorithm, the algorithm can refer to Zhang XD version of the principle of modern signal processing, absolutely can run the program with the book is very easy to understand, and can become a little change to change the basic ESPRIT algorithm.)
