·摘 要:针对声发射管道泄漏检测过程中的噪声干扰问题,对基于小波包和经验模态分解(EMD)的声发射信号处理方法进行了研究。采用小波包分解算法和经验模态分解都可以对管道泄漏声发射信号进行分解,但分解结果却存在一定区别。EMD是近年来非平稳信号...
EMD/HHT是一种处理非线性非稳态信号的经典算法,自98年提出以来已经获得广泛的使用,作者huang曾经因次获得NASA的最高奖。
探地雷达回波信号是一种非平稳非线性信号,其中不仅包含地下埋藏物的目标信号,还包含有可能掩藏目标信号的直达波信号,给目标的识别带来困难。文中采用HHT方法对探地雷达回波信号进行特征分析,提取回波信号的IMF分量的瞬时频率作为特征向量。实验结果...
