Paper Abstract

A new evaluation method is proposed for single polarimetric speckle filters of Synthetic Aperture Radar (SAR) images, including two steps: measurement and aggregating multicriteria. In accordance with three properties of a good speckle filter: speckle reduction, feature preservation and radiometric preservation, six measures are selected: Equivalent Number of Looks (ENL), Target-to clutter Ratio, Radiometric Loss, Bias of Mean Value, Bias of Spatial Resolution, Bias of Peak Sidelobe Ratio, where the last two criteria are firstly addressed in this presentation. In multicriteria decision making, Ordered Weighted Averaging (OWA) operator is used to aggregate the performance preference matrix induced by measures. The experiment result of real and synthetic SAR images for five speckle filters conforms to that of visual comparison.
