摘　　要：对SAR干扰效果的评估是目前的一个研究热点。在依据SAR图像受干扰情况评估SAR干扰效果的过程中,人的主观因素占主导地位。对于这种不确定性的评判,该文介绍了一种基于模糊推理的SAR干扰效果评估方法。首先,建立了SAR干扰效果评估指标;接着,借助相关领域专家的经验知识和推理规则,采用定性与定量相结合的方法,建立了模糊推理数学模型;最后,利用所建立的指标和模型进行干扰效果综合评判,得到了合理的、令人满意的结果。At present, assessment of effect on jamming a synthetic aperture radar（SAR） is a hot topic, One＇s subjectivity is a dominant factor in course of jamming effect evaluation based on the jammed SAR images. To handle this kind of uncertain assessment, this paper discusses a method to evaluate the jamming effect on SAR based on fuzzy reasoning. Firstly guideline system of assessment is constructed. Secondly, with the help of experience knowledge and reasoning rules given by experts in the associated research field, a fuzzy reasoning mathematic model is established by combining qualitative and quantitative measures. At last, some reasonable and satisfied conclusions have been reached in the process of synthetic evaluation of jamming effect by means of the guidelines and mathematic model.
