Assume that in a refraction survey arrival times of refracted waves have been observed along at least two lines of different azimuth, and on at least one of the lines, the “main” line, observations in reversed directions have been taken. The set of observed arrival times is complete (i.e. there is a one-to-one relationship between interfaces in the ground and branches of the travel time curves and all segments of travel time curves are straight (thus the media between the interfaces are homogeneous). Moreover, we assume isotropy for all layers (this assumption can be replaced by that of independent information about shape and orientation of the slowness surfaces of the media).
