A Quality Evaluation Method of SAR Image Based on Grayscale Image and Electromagnetic Scattering Characteristics

摘要

In order to get the quality evaluation of Synthetic Aperture Radar (SAR) image, the essay proposed a quality evaluation method in three steps. First, a normalized evaluation index system combining the characteristics of grayscale image and electromagnetic scatter is established using the experience of Analytic Hierarchy Process (AHP). Then, the relationships between indexes and image quality are analyzed, as the distribution ranges and variation principles of indexes are determined by statistics. Eventually, the quality evaluation method is proposed, and some simulation results are presented. The method raised in this paper is simple, effective and robust, applied well to image quality assessment that has reference particularly.
