ABSTRACT
The ultrawideband (UWB) ground-penetrating radar (GPR) allows nondestructive control and search of different objects buried in ground. However, it can be also used for characterization of ground. Sometimes, GPR allows detection of water or oil leakages from buried pipelines or determination of soil moisture content in a variety of Želds such as hydrology, agronomics, etc. Because interpretation of radar data requires complicated processing, which usually can be made only by experienced operator, the automation of object-detection process and ground-permittivity measurement using GPR images is of great commercial interest. This chapter presents methods to automate the evaluation of ground characteristics by permittivity estimation. The relative permittivity ɛ is one
