基于结构相似度的SAR干扰效果评估方法
Evaluation of Jamming Effect on SAR Based on Method of Structural Similarity
摘要
Abstract
Without considering correlation of pixels and the perceptual characteristics of human vision system (HVS) , traditional synthetic aperture radar (SAR) image quality evaluation indexes are limited , so that the subjective and the objective means can not come to consistent. A new evaluation method which combines the characters of the subjective and the objective is proposed. This method can not only make good use of structure similarity as juncture between the subjective and the objective evaluation methods, but also utilize the character of local variance similarity which matches with high frequency information in image. Finally, the modified evaluation model is obtained by nonlinear combination. Simulation results show that the new method has an obvious advantage over traditional evaluation methods. Besides reflecting the influences of jamming on ROI in the image, it can keep identical to HVS, and furthermore, it improves the efficiency and accuracy of entire evaluation system.关键词
