Time-Frequency Analysis of Seismic Signals Based on WOA-Optimized VMD

This paper proposes a novel approach for seismic signal processing using Whale Optimization Algorithm-based Variational Mode Decomposition (WOA-VMD). The method adaptively optimizes key VMD parameters, including the number of modes and the penalty factor, to achieve effective mode decomposition and noise suppression. Experimental results on both synthetic and real seismic data demonstrate that WOA-VMD outperforms conventional timefrequency analysis methods in terms of mode separation quality and time-frequency resolution. The proposed method provides a reliable tool for high-resolution seismic interpretation and offers significant potential for applications in hydrocarbon exploration
