The detection of buried objects using Ground Penetrating Radar utilizes hyperbolic curves visualized by the variation of reflected signals due to the relative distance difference between the antenna and the buried objects.However, these hyperbolic signals are also created by various objects buried underground, making it difficult to identify and detection target.This difficulty can be solved through a plan-view image viewed from above along with the same hyperbolic image for each channel as the existing one created based on the 3D data of multi-channel GPR.In this paper, we discussed the transmitter-receiver antenna array and signal processing procedure for constructing plan-view images using multi-channel GPR for underground object detection.And we also verified the effectiveness of the plan-view images constructed using multi-channel GPR survey data through detection tests on object with known sizes.
