This study presents a radial-component predominant-mode (RCPM) inversion framework designed for DAS-based surface-wave analysis, considering source–receiver directivity and modal sensitivity of the Rayleigh-wave radial component.

During deep subsurface exploration, modal osculation occurs due to high impedance contrast, which leads to mode misidentification. This paper proposed predominant mode inversion to address and overcome this challenge.

This paper proposes effective mode inversion framework for active surface wave analysis, addresses near-field effect, modal superposition and mode kissing.

This paper proposes a high-resolution dispersion imaging method using Modified S-transform. It effectively processes noiseless and noisy records.

In this paper, we showed that the spectral whitening can adequately eradicate most of the shortcomings associated with different wavefield transformation techniques.
