数字水印图片信息隐藏在载体图片的最低有效位lsb，直接替换，该方法简单易操作，鲁棒性很差，经不起加噪，滤波，剪贴等攻击(digital watermarking Photo vector information hidden in the lowest effective photo-lsb direct replacement, The method is simple and easy to operate, robust poor and the inability to increase noise, filtering, clippings and other offensive)

说明：  讲述信号处理中互相关技术的使用原理，并以超声波为例子，来说明其实用性。(About the cross-correlation signal processing techniques in the use of principles, and to ultrasound as an example to illustrate its practicability.)

利用FFT快速计算，线性排列阵子方向图。( This function computes and returns the gain radiation pattern for a linear array It uses the FFT to computes the pattern *INPUTS********** Nr ==> number of elements dolr ==> element spacing (d) in lambda units divided by lambda theta0 = steering angle in degrees winid ==> use winid negative for no window, winid positive to enter your window of size(Nr) win is input window, NOTE that win must be an Nr X 1 row vector nbits ==> number of bits used in the pahse shifters negative nbits mean no quantization is used *OUTPUTS****************** theta ==> real-space angle patternr ==> array radiation pattern in dBs patterng ==> array directive gain pattern in dBs ***************************************** )
