- 有两个程序一个是关于frft的源程序，一个是应用frft对线性调频信号进行检测的程序，原理是以变换阶数（不同的分数阶域）为变量对观测信号进行分数阶变换，形成信号能量在时频平面上的二维分布，在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。-There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle

- 数字水印文件和数字水印命令是数字水印技术在军事应用的两个重要应用。本文以一种基于分数阶傅里叶变换 (FRFT)的数字水印算法，使用chirp信号作为水印信息，嵌入到图像的分数阶傅里叶的加密域中。该算法有效地利用水印的 嵌入位置和FRFT的阶次作为密钥的同时，还利用chirp信号在分数阶傅里叶域的特点，可以很方便的检测到水印，具有良好 的不可见性和安全性的同时，还能够抵抗很强的JPEG压缩和噪声的攻击，对剪切、滤波等操作也有一定的鲁棒性。-Watermarking files and
