Ground penetrating radar has come to public attention in recent criminal investigations, but has been a developing and maturing remote sensing field for some time. In the light of recent growth of the technique to a wide range of applications, the need for an up-to-date reference text has become pressing. This fully revised and expanded edition of David Daniels' bestselling text, Surface-Penetrating Radar (IEE, 1996) presents, for the non-specialist user or engineer, all the key elements of this technique, which span several disciplines including electromagnetics, geophysics and signal processing. The book enables the user to assess the potential of the technique and apply it effectively with current technology. The new edition is a greatly expanded treatment of a radar technique that penetrates the surface of the ground or man-made structures and contains many additional contributions by leading experts in the field. Ground penetrating radar is increasingly used to examine archaeological sites, engineering structures (e.g. bridges, roads) etc., and has come to some prominence in forensic investigations. GPR is also used for the detection of landmines. The book presents the principles with an emphasis on practical applications and also includes a CD with many examples of GPR data and processing techniques as Mathcad worksheets.
