Abstract

     Many engineering decisions must be made on the basis of non-destructive evaluations (NDE). In addition, these assessments should be based on an acceptable engineering criterion. Although, the use of any inspection system is costly, but one of the obvious benefits of employing accurate non-destructive tests, is identification of deficiencies which leaving unidentified in the environment will cause events and as a result, a lot of financial and life losses. The geophysical method called Ground-penetrating radar (GPR) is a new, useful and very powerful method for non-destructive testing of retaining walls, buildings, bridges, tunnels, pavements, roads, railways, pipelines, tunnel lines, highways, substructures, sewage pipes, various types of other installation pipes and man-made artifacts such as concrete, asphalt, rebar, bricks and so on (Ahmadi et al., 2014; Annan et al., 2002).
     This method produces very high-resolution subsurface images via sending high-frequency electromagnetic waves (usually in the range of 1 MHz to more than 1 GHz) into the earth and recording reflected waves transmitted through low-loss dielectric media (Annan, 2001).
