FFT简称为快速傅里叶变换，是DTF处理的一般实现方法，一维距离成像就是对差拍信号进行FFT变换，变换所得到的幅值图像横坐标为距离信息，纵坐标为幅值信息，通过一维仿真，我们可以看到目标距离相对应的幅值信息。(FFT referred to as fast Fourier transform, is DTF processing general method, a d imaging is difference from pat signal FFT transform)

用于对信号的HHT分析，可得到IMF、功率谱、边际谱等图(HHT for signal analysis, obtained IMF, power spectrum, marginal spectrum, etc. Figure)

天在维普下载了一篇SPIHT算法改进的论文，（耿兴云，《基于改进SPIHT的静态图像编码》，电脑知识与技术：学术交流-2007年5期），我根据该文提出的改进算法，用Matlab来实现，却发现改进算法的程序运行速度比原算法还要慢，希望有兴趣的朋友进来看看，评论一下原因。(Days in the VIP downloaded a SPIHT algorithm to improve the paper, (Gengxing Yun, " based on improved SPIHT still image coding," Computer Knowledge and Technology: 5-year academic exchange-2 007), in accordance with this paper the improved algorithm Matlab to achieve, but found that the improved algorithm runs faster than the original algorithm is also slow, hope to have interested friends come to see, comment on why.)
