I recently came across https://www.space.com/mars-subsurface-map-from-insight-wind-sound?fbclid=IwAR2_eh-gWAFu1PTfjJzG-xIAzUlOAbF0YLRJPfGStgLpzjTQt2AwNMusdS0 and thought I wonder how that works. Looking at the paper gave no details but by going back through the refereces I found https://www.academia.edu/26078683/Frequency_dependent_traveltime_tomography_using_fat_rays_application_to_near_surface_seismic_imaging which seems to give an explanation ('seems' and 'explanation' may be optimistic as I have to admit not understanding most of what is written). Does anyone know of its possible use (or of a similar technique) to detect caves?
