A circular survey for 3D GPR using the linearly polarized antenna is proposed to detect and map the hidden cylinders. The backscattering signal from cylinders may strongly depend on the orientation of the cylinder relative to the antenna. The circular survey can conform to the optimal measuring condition that the long axis of the bow-tie antenna oriented is parallel to the long axis of the cylinders,...
Circular cylinders are important classes of environmental and engineering targets which act as depolarizing features, such as pipes, cables, rebar and tree roots. Two-dimensional plan survey using the linearly polarized Ground Penetrating Radar (GPR) is verified as an effective method to obtain the full-resolution image of subsurface objects and architecture. Compared to the regular measurement, a...
