BURIED OBJECT SEARCHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a buried object searching device, capable of easily measuring a buried object and capable of appropriately searching a buried tube with no experience required for judging the buried tube. SOLUTION: A transmission antenna 2 and reception antennas 4 and 5 whose polarization directions crossing each other are provided on a vehicle 7. The electromagnetic wave is transmitted toward a ground surface from the transmission antenna 2 while moving. The electromagnetic wave reflected on a buried tube 15 existing underground is received with reception antennas 4 and 5. A calculation part 13 calculates an azimuth intensity pattern of the reflection wave based on the reception signal of the reception antennas 4 and 5 and the mutual positional information of the transmission and reception antennas. The position and direction of the buried tube 15 are estimated from the azimuth intensity pattern.
