Analysis Methods for the Polarimetric WISDOM Radar aboard the ExoMars Rover
Résumé
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).
