ABSTRACT
Using radio-wave ground-penetrating radars is considered as the most promising direction in sub-surface detection of dielectric objects. Ground-penetrating radars, called also sub-surface or geo-radars, are widely used for archaeological purposes: for studying archaeological ground layers, searching for artifacts, and so forth. A convenient tool for investigating inhomogeneities hidden underground is the synthetic aperture radar technique in the wide frequency band. The use of ground-penetrating radars dates back to 1971, when the first measurements of sea ice thickness were performed, based on the video pulse method introduced by M. I. Finkelstein in 1969. Ground-penetrating radars are most widely used today in rail and road inspection, locating and monitoring communication lines and archaeological objects, estimating snow and ice cover, monitoring concrete structures, horizontal directional drilling and geological surveys, and searches for hidden objects.
