Development of a UWB GPR system for detecting small objects buried under ground

A ground penetrating radar (GPR) using short-pulse is developed in order to detect small and shallow metal objects buried under the ground. A bistatic mode in which the GPR system uses separate transmitting and receiving antennas is applied. A modified fat dipole antenna is developed for the transmitting and receiving antennas,. The prototype of the system is tested in real environment and 2D visualization of raw data is achieved. It is shown that the developed system has a good ability in detecting underground metal objects, even small targets of several centimeters.
