摘　　要：干扰效果是衡量干扰模式有效性以及雷达干扰设备性能的一项重要综合性指标。干扰效果评估对电子对抗设备的研制、试验乃至实战都十分重要。首先将现有评估方法划分为主观评估方法和客观评估方法两类,其中后者主要包括基于SAR图像质量指标的评估方法、基于目标检测概率的评估方法及基于信息熵的评估方法;其次简单介绍了主客观评估方法的具体实现步骤;最后提出了一种组合与优选的评估方法。经过一系列的仿真验证,该方法不仅能够有效地避免单一评估方法的局限性,而且还兼顾了主客观联合评估的优势,极大地丰富了SAR干扰评估的手段。The jamming effect is one of the important synthetic indexes, which can be used to scale the validity of jamming modes and the performance of jamming equipments. Jamming effect evaluation is also very important for the development test, and even actual combat of the electronic counter-measurement equip- ment. The paper firstly classify current evaluation methods as the subjective and the objective evaluation methods. The latter includes the evaluation methods based on imaging quality index of SAR, the evaluation methods based on the probability of target detection, and the evaluation methods based on information entro- py. Then the paper simply introduces idiographic process of the subjective and the objective evaluation meth- ods. In the end, a new method of combination and optimization is proposed, which can avoid the limitation of single evaluation method, and obtain the combination superiority of the subjective and objective evaluation methods. So this new method ulteriorly enriches the means of jamming evaluation to SAR.
