| | Abstract | | In general, ground penetrating radar (GPR), one of geophysical exploration methods, uses only information on the arrival times of reflected waves. Therefore, it is still difficult to accurately clarify underground structure and physical prosperities. In order to address this problem, use of information on the magnitude and waveform of the reflected waves is expected to be effective in addition to the travel time information. Thus, this study aims to develop a method with multiple antenna directions to obtain more underground information. By comparing the data obtained from a model experiment with a simulation result, effectiveness of the GPR using the polarization characteristics and also, validity of the simulation method are examined. As the result, the antenna arrangement and the amplitude of the reflected wave related, suggesting that the relative permittivity of the ground can be estimated. |
