In this paper, we describe the capabilities of the fully polarimetric antenna system of the WISDOM GPR aboard the ExoMars rover in terms of a polarimetric data analysis as well as the setting and procedure for left-right-detection and entropy-based classification of (buried) objects. By means of different experiments (laboratory, artificial environment, and field tests [3]) the principles are validated. The evaluation of radargrams allows the lateral discrimination of the position of scatterer with regard to the path of the rover. A rough classification of objects and single subsurface features is performed by applying the entropy-alpha decomposition (H-α).
