N2 - The compact polarimetric mode of synthetic aperture radar (SAR) provides an approach of polarimetric observation by a reduced PRF and doubled swath width, which has already proven its advantage compared with the traditional full-polarimetry (FP) mode in several occasions. In this paper, a quantitative evaluation method for the compact polarimetric SAR image reconstruction is proposed. The quad-pol data are reconstructed by the iteration algorithm proposed by Souyris et al.. Analysis is carried out on the performance of the algorithm based on information-theoretic analysis. The performance of the algorithm is evaluated quantitatively by implementing information entropy, mutual information, Kullback-Leibler distance and difference of entropy between the reconstructed and original FP data. Based on this analysis, several key parameters of this algorithm is verified and optimized.
