MANUAL GUIDE SCAN TYPE UNDERGROUND EXPLORATION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a manual guide scan type underground exploration apparatus having high interference resistance.

SOLUTION: The underground exploration device for performing a scan with a manual guide has an operable housing formed for separately and remotely guiding the wall surface to be investigated with a predetermined wall surface distance and a sensor means capable of sensing it in a high frequency electromagnetic wave region. An electromagnetically effective shielding means is installed for shielding the wall surface distance from electromagnetic interference wave in the high frequency region of the underground exploration device, in at least most surrounding region of shield contours for surrounding the sensor means from the outside.
