Entropy, anisotropy and alpha (H/A/α) parameters of the target decomposition in synthetic aperture radar polarimetry (PolSAR) are valuable tools for the assessment of the physical parameter retrieval. However, the speckle emerging in SAR images decreases the accuracy of image classification and segmentation. Consequently, it should be filtered correctly. In fact, insufficient averaging generates biased...
Entropy, alpha, and anisotropy (H/α/A) parameters of the polarimetric target decomposition have shown their capacity for polarimetric synthetic aperture radar (SAR) image analysis. However, due to insufficient averaging, these parameters are biased. The literature shows that the anisotropy bias removal is not resolved. Based on simulation results, we present a simple technique for the removal of the...
