摘要
本文分析了用经验模态分解 (EmpiricalModeDecomposition,EMD)方法处理非平稳噪声信号的基本原理 ,并利用EMD方法有效地消除了高斯白噪声对瞬态散射回波的干扰 .文中以一人工合成瞬态回波为例 。
The theory of non-steady noisy signal processing based on EMD method is discussed,and this method is used to recover signal from transient scattered response contaminated by Gaussian white noise.The effectiveness of the proposed method is verified with a synthetic transient scattered response.
