Resolving phase wrapping by using sliding transform for generation of dispersion curves
Jyant Kumar,Tarun Naskar +1 more
TL;DR: This work has developed a new method that is fast, accurate, and generally resolves the unwrapping of phase with the use of just two sensors, provided the signal-to-noise ratio remains high.

Multichannel analysis of surface waves
TL;DR: In this article, a multichannel shot gather is decomposed into a swept-frequency record, allowing the fast generation of an accurate dispersion curve, which can then be examined and its effects appraised in both frequency and offset space.
