BURIED OBJECT EXPLORATORY DEVICE AND BURIED OBJECT EXPLORATORY METHOD

摘要

PROBLEM TO BE SOLVED: To provide a buried object exploratory technique capable of exploring a buried state of either a structure or a plurality of buried objects buried underground.;SOLUTION: A buried object exploratory device 10 explores a buried state of either a structure 11 or buried objects in a target exploratory area with radio waves transmitted to and reflected from the buried objects. The buried object exploratory device comprises: signal generation means 14 to generate high frequency signals; radio wave transmission means 15 to transmit radio waves of the generated high frequency signals to the target exploratory area; radio wave receiving means 16 to receive reflected waves which are the radio waves transmitted to and reflected from the buried objects; analogue-digital conversion means 18 to convert the high frequency signals of received radio waves into digital signals; and buried object position calculation means 20 to calculate a distance to the structure 11 or the buried objects in the target exploratory area on the basis of signal levels of the recorded digital signals and propagation time of the radio waves. A distance between the radio wave transmission means 15 and the radio wave receiving means 16 can be adjusted according to a size of the buried object in the target exploratory area.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
