NewEnvelopeAlgorithmForHilbert-HuangTransform

您好： 这个matlab程序是用周期循环检测算法检测：首先运行a.m程序，通过此程序运算得出循环频率a值；再运行zhouqi.m程序，对a值进行确定，通过周期循环算法对信号进行检测； (Hello: This procedure is used matlab cycle detection algorithm: First run a.m program, obtained through the operation of this procedure cyclic frequency of a value to run zhouqi.m procedures, a value determined by the signal cycle algorithm detection )

扩展的虚拟同步（Extended Virtual Synchrony），也称为 TOTEM 协议 Y. Amir 等，"The Totem Single Ring Ordering and Membership Protocol" L.E. Moser 等，"Extended Virtual Synchrony" Corosync 是 TOTEM 协议的一个开源实现，当前 RedHat 等提供的企业集群使用它作为一致性协议。

该程序中包含了小波包分解和重构程序、单尺度分解、多尺度分解等，还有一些试验数据，对初学者有很大的帮助。(The program includes a wavelet packet decomposition and reconstruction program, a single scale decomposition, multiscale decomposition, there are some experimental data, for beginners is a great help.)

对于InSAR 系统,当波长较长时,干涉图条纹频率较低,相位解缠容易,但反演的高程精度较低 而当波长较短时,干涉图条纹频率较高,相位解缠困难,但反演的高程精度较高. 为了充分利用多波段 InSAR 干涉相位之间的互补信息,设计了利用中国余数定理的多波段InSAR 相位解缠方法,采用由DEM 仿真的多波段干涉图进行了相位解缠实验,得到了理想的解缠结果,成功解决了因地形起伏较大或基线较长而引起的干涉相位欠采样处的相位解缠难题.(For the InSAR System熏when the wavelength is longer熏the frequency of fringes will be lower熏the phase unwrapping will be easier熏and the accuracy of derived heights will be lower. However熏when the wavelength is shorter熏the frequency of fringes will be higher熏the phase unwrapping will be more difficult熏and the accuracy of derived heights will be higher. In order to make the best use of compensatory information in multi鄄band InSAR phases熏the phase unwrapping algorithm with the Chinese Remainder Theorem for multi鄄band InSAR is designed. The multi鄄band interferograms simulated from DEM are applied to do phase unwrapping experiments. The satisfying phase unwrapping results are obtained. The difficulty in phase unwrapping of sub鄄 sampling interferometric phases due to great hypsography or longer baseline is removed.)
