是本科毕设的题目，相控阵天线的方向图（切比雪夫加权），包含特征值与特征向量的提取、训练样本以及最后的识别，是机器学习的例程，采用累计贡献率的方法，基于人工神经网络的常用数字信号调制，信号处理中的旋转不变子空间法。( The title of the commercial is undergraduate course you Phased array antenna pattern (Chebyshev weights), Contains the eigenvalue and eigenvector extraction, the training sample, and the final recognition, Machine learning routines, The method of cumulative contribution rate The commonly used digital signal modulation based on artificial neural network, Signal Processing ESPRIT method.)

快速NCC(normalized cross correlation)算法实现。比matlab自带的normxcorr2 快10-20倍。在windows Unix环境下c语言，和matlab编译通过。(use Matlab on Windows or Linux or Mac OS X and want fast (exact, general-case) normalized correlation (NCC) code right now, then download it and enjoy the large performance gain over Matlab s normxcorr2 (demo included). For the brave (and/or masochistic) there is B), however, it is unlikely you will do better than the above. Thanks to Liang Jin for making the OS X binary (his performance comparison graph on a PowerPC). )
