Robustness of Model-based PolSAR Decompositions

Abstract:
We propose to test model-based polarimetric decomposition techniques for robustness to variations of the underlying in-scene scattering mechanisms. The accuracy and robustness of the decomposition results are determined from simulated data sets. The simulation input parameters, e.g. volume scattering model, polarimetric signal-to-noise, etc., are known and thus provide the “ground truth” for comparison to model-based decomposition results. The observed correlations between simulation and model results allow estimates of model accuracy and model robustness.
