Imaging dispersion curves of passive surface waves - MASW

Webfrequency–velocity (f-v) domain is a meaningful and challenging task in the MASW method. High-resolution image of dispersive energy can help us correctly pick dispersion curves and separate the fundamental mode from higher modes of surface waves. Modeling results (PARK et al., 1998) show that resolution of the dispersion image in the WebThe way dispersion analysis is executed has been changed so that the previous sequence of 'Preprocess-->Overtone-->Run-->Save' has been divided into two separate steps: (1) … hope all is good or hope all is well
