Abstract

To evaluate the performances of speckle filters for polarimetric synthetic aperture radar images

a unified evaluation framework that includes both the polarimetric information and spatial information is established. The very high resolution SAR image will be employed as the experimental data. The polarimetric and spatial indicators are listed

and then the procedure for applying the evaluation is demonstrated. The absolute relative bias is suggested for the purpose of evaluating the parameters. The very high resolution image provided by UAVSAR system is designated as the experimental data and then six classic speckle filters have been tested in respect of their performances. The results of the evaluation

as an important reference

are beneficial to the users who will design some polarimetric applications therewith.
