SYSTEM AND METHOD FOR EXPLORING UNDERGROUND ELECTRICAL PROPERTIES USING GROUND WAVE

摘要

The present invention extracts a ground wave from a ground wave, an air wave, and an underground scattered wave that can be obtained during a ground penetrating radar survey and calculates a peak value, a sign, a time point, The present invention relates to a system and method for exploring an underground physical property using a ground wave, which performs precise exploration of electrical properties such as permittivity and electrical conductivity of an underground medium. A ground wave exploration system using a ground wave according to the present invention includes: a transmission antenna configured to transmit a GPR signal; A receive antenna configured to receive an airwave, a groundwave, and an underwave scattered wave; An antenna interval adjusting unit configured to adjust a horizontal interval between the transmitting antenna and the receiving antenna; And controls the antenna interval adjusting unit to adjust the horizontal distance between the transmitting antenna and the receiving antenna to a predetermined length so that the air wave and the ground wave are separated from each other in the underground medium and are received through the receiving antenna, A control unit for transmitting a GPR signal and receiving an airwave, a ground wave, and an underground scattered wave through the reception antenna; And a signal processor for receiving an air wave, a ground wave, and an underground scattered wave from the control unit, and then extracting a ground wave and analyzing the underground physical property.
