Reconstruction of subsurface radio holograms fully and partially measured by different methods

Abstract

Reconstruction of measured holograms is performed by the backward propagation method and by means of a preliminary measured instrument function (IF). It is shown that the results of the reconstruction can be improved by reducing the IF measuring error, e.g., by averaging over a ring. It is established that images of a part of subsurface radio holograms can be obtained not only if the known part of a hologram is an entire fragment but also if the measured points of the hologram are not nearest neighbors of each other.
