高阶谱分析工具6，适用于阵列信号处理、雷达信号处理等。(High-order spectral analysis toolbox for array signal processing, radar signal processing.)

说明：  lower的原版关于sift算法的资料，很难找的哦。本文非常详细的介绍了sift算法，并与常用的边缘检测算法作了比较，是学习sift算法的好资料。(lower of the original information on the sift algorithm, it is difficult to find, oh. This very detailed introduction to the sift algorithm, and with commonly used edge detection algorithms are compared, is the learning algorithms sift the good information.)

用声卡采集的模拟信号作为输入,然后fft变换,并且图形化的显示出来(sound card collection with the analog signal input, and then fft transform, and the graphics displayed)
