Evaluation Method of SAR Jamming Effect Combining Hierarchical Visual Features and Structural Similarity

提出了一种结合分层视觉特征和结构相似度的SAR干扰效果评估方法。该方法以结构相似度为基础,通过视觉纹理特征模型对结构相似度进行修正。利用小波变换模型模拟人类视觉的多层处理机理,结合视觉敏感性模型得到SAR干扰效果的评估参数。通过与SSIM-V方法和SSIM-T方法对比实验可知,该方法在CC、RMSE、SROCC和OR等指标上都具有更优秀的干扰效果评估能力,在SAR干扰效果评估领域具有较大的应用前景。

A method combining hierarchical visual features and structural similarity for evaluating the effect of SAR Jamming is proposed.Based on the structural similarity,the method uses the visual texture feature model to modify the structural similarity.The wavelet transform model is used to simulate the multi-layer processing mechanism of human vision,and the visual sensitivity model is used to obtain the evaluation parameters of the SAR jamming effect.Compared with the SSIM-V method and the SSIM-T method,it can be seen that the method has a better performance in assessing the jamming effect on CC,RMSE,SROCC,and OR,and has a greater application prospect in the field of SAR jamming effect evaluation.
