基于EEMD的SAR海洋内波参数反演
Extracting Internal Wave Parameters From SAR Image Based on Ensemble Empirical Mode Decomposition
摘要
Abstract
Empirical mode decomposition (EMD) sometimes cannot reveal the non-stationary signal characteristics accurately because of the problem of mode mixing and edge effect. Ensemble empirical mode decomposition (EEMD) was developed recently to alleviate this problem. Utilizing the advantage of EEMD, this paper proposes a new EEMD-based extracting method for internal wave parameters from SAR image. The application results indicate that, the EEMD is superior to the wavelet method and the EMD method; EEMD can eliminate mode-mixing, the extracted internal wave component is close to the true physical nature, and the internal wave amplitude retrieved by the method is in agreement with the empirical data.关键词
