Review and Prospects of Ground Penetrating Radar Technology

The past 100 years has witnessed the utility of ground penetrating radar (GPR) to solve a variety of problems in subsurface characterization and there is an overall sense of the technology reaching a level of maturity. The brief history of GPR is reviewed, including its hardware system, data processing techniques and various practical applications, both the value and the limitations of the nondestructive testing method are analyzed and its current trends of progress was discussed.
