摘　　要：SAR探测距离是评判SAR系统性能的关键指标,不同于普通雷达给出的针对点目标的探测数据,SAR系统给出的是面目标的雷达图像,因此对其探测距离的评估也要有别于普通雷达,因从其雷达图像质量入手进行考核其作用距离。提出了基于图像解译概率的SAR探测距离评估模型,并在此基础上分析研究了评估过程中相关参数的测量方法。SAR探测距离的评估技术研究成果已在外场试验中得到应用,具有一定的推广利用价值。Synthetic aperture radar（SAR） detection range is the key guideline of judging SAR system capability. Different from common radar, which gives point target detection data, SAR system gives area target radar image, so the assessment of its detection range is different from that of common radar. To assess its range should start from its radar image quality. The SAR detection range evaluation model is raised based on image interpretation probability, the measuring methods of parameters in evaluation process are analysed and researched. SAR detection range assessment technique has been applied in field test and has the promotion use value
