The two crucial tasks of the noninvasive method, namely sub-surface imaging and characterization of materials, are best accomplished by GPR methods that exploit redundant information. In this Section we show examples of successful application of such techniques, in particular linear multi-fold, azimuthal multi-fold and multi-polarization (multi-component) methods. Focusing of the radar wave field are clutter reduction are the key issues in image enhancement. Focusing is based on migration techniques that require knowledge of the velocity of radar waves in the sub-surface. Clutter reduction benefits from multiple data from the same sub-surface location. Multi-fold methods can provide an adequate solution for both problems.

Abstract
The two crucial tasks of the noninvasive method, namely sub-surface imaging and characterization of materials, are best accomplished by GPR methods that exploit redundant information. In this Section we show examples of successful application of such techniques, in particular linear multi-fold, azimuthal multi-fold and multi-polarization (multi-component) methods. Focusing of the radar wave field are clutter reduction are the key issues in image enhancement. Focusing is based on migration techniques that require knowledge of the velocity of radar waves in the sub-surface. Clutter reduction benefits from multiple data from the same sub-surface location. Multi-fold methods can provide an adequate solution for both problems.Pubblicazioni consigliate
