How does one determine the optimum offset in a seismic survey?
I was going through a report on MASW (Multi Station Analysis of Surface Wave) and found this
"To avoid the aliasing in the space domain, geophone spacing (Δx) needs to be less than half of the minimum wavelength of interest but channels of the…
