A solution to the blind‐zone problem by modeling of postcritical reflections

Abstract

An approach for solving the blind‐zone problem in seismic refraction prospecting is investigated. Hidden layer(s), if present in blind zones, can be identified with the help of postcritical reflections. These arrivals carry high energy and are easily identifiable on seismograms. Forward modeling techniques may be employed to determine the hidden‐layer parameters even in complex situations.
