Abstract
En 中文
• An advanced decomposition technique, termed 3D-SRMD, is introduced. • Chirp rate dimension is incorporated in SRMD to disentangle crossover modes. • A novel random feature strategy is designed to improve approximation accuracy. • 3D-SRMD shows high accuracy and strong robustness on crossover modes separation.
Keywords:
