Orthogonal polarization approach for three dimensional georadar surveys

This paper presents the results obtained from the combination of co-pole GPR data collected along perpendicular directions. The scope is to demonstrate how this approach can efficiently overcome pitfalls of traditional single orientation surveys and ensure target detection regardless of their geometrical and physical properties. This is of high importance especially when acquiring across targets that show directional dependencies of the preferential scattering components. This work relies on four field examples, each of them illustrating in detail the improvements and the advantages that a single image resulting from the stack of the two volumes can show, in particular what concerns target imaging.
