ENHANCEMENT-TYPE TRANSCEIVER FOR SEISMOELECTRIC SURVEY

摘要

The present invention relates to a signal-enhancing transceiver for seismoelectric survey capable of removing noise caused by surrounding electromagnetic waves and enhancing signals transmitted from underground. The signal-enhancing transceiver for seismoelectric survey according to the present invention comprises: a hitting hammer; a hitting plate installed on the ground to receive hits from the hitting hammer and generate artificial seismic wave signals; an electrode antenna separated by a predetermined distance from the hitting hammer and partially inserted into the ground to receive the artificial seismic wave signals transmitted underground; and a signal amplifier connected to the electrode antenna to amplify the received artificial seismic wave signals. The electrode antenna is composed of an electrode bar inserted into the ground to receive the artificial seismic wave signals; an insulating cover formed of a nonmetallic material and enveloping the outer circumferential surface of the electrode bar; and a shielding cover formed of a metallic material and enveloping the outer circumferential surface of the insulating cover. Noise can be removed effectively as the electrode bar is longer than the insulating cover and the shielding cover.
