Evaluation method of similarity between two synthetic aperture radar (SAR) images plays a key role in the SAR raw data simulation and the analysis of SAR imaging quality. Although the similarity between two SAR images is intuitive, it still lacks objective and quantitative method to evaluate it. Thus, an evaluation method named Otsu-PHash is proposed in this paper from the perspective of image similarity to solve the problem. The key steps of the proposed Otsu-PHash method are threshold segmentation and similarity comparison. Finally, the numerical experiment verified that our proposed method can be applied to evaluate similarity of the two SAR images.
