Radar polarimetry analysis applied to fully polarimetric Ground Penetrating Radar

Polarimetric decomposition techniques have been applied in remote sensing in the area of air-space-borne radar and have achieved much progress in recent years. However, very few apply these polarimetric decomposition techniques to the Ground Penetrating Radar (GPR).We currently apply GPR data sets to characterize and classify the subsurface targets using Pauli decomposition method. The Pauli decomposition method provided important radar polarimetry information of subsurface targets, and the Pauli decomposition method made a significant contribution to understanding the scattering mechanisms from different subsurface targets with different properties. Analyzing polarimetric attributes of subsurface targets provides facilitates for classifying subsurface targets. Because some methods only can identify the approximate outline of subsurface targets, but can not classify the targets such as imaging technique that can only identify the outline of subsurface targets, but can not classify targets. So we apply Pauli decomposition for classifying subsurface targets and this analysis result is relatively good. The decomposition technique plays a key role for classifying subsurface targets such as metal surface plate, dihedral, metal ball and other subsurface targets. This paper mainly applies Pauli decomposition method to recognize subsurface metal surface plate, subsurface dihedral, subsurface metal ball, subsurface metal bucket, and subsurface chaotic scattering target. This decomposition technique provides valuable information for the study of properties of the subsurface targets.
