Full polarimetric GPR data decomposition and imaging

Polarization is a property of electromagnetic wave that generally refers to the orientation of the electric field vector, which can be used to characterize target properties by polarimetric radar. Polarimetric decomposition methods have been common in the terrain and land-use classification based on plolarimetric synthetic aperture radar data. However, the technique has been less common in the ground penetrating radar (GPR) community. In this paper, we introduce the polarimetric decomposition technology into the full polarimetric GPR data analysis. Using the polarimetric decomposition, we extract the polarimetric information of subsurface targets. Also migration can be used to the full polarimetric GPR data, and target imaging can be obtained. Laboratory experiment results show that we can improve the classification of subsurface targets by combing the polarimetric information and imaging.
