摘　　要：目标SAR(合成孔径雷达)数据库是目标特征识别与提取研究的基础,目标SAR数据库试验获取的关键是地面目标摆放和SAR载机航线设计。为了获取目标多姿态SAR数据库,首先研究了地面目标距离间隔和角度间隔的配置要求,给出了SAR载机航线设计原理,包括航线长度、航向角度间隔、成像中心直角坐标系试验航线设计;推算出地心惯性坐标系下航线经度、纬度和海拔计算方法,开发了自动化试验航线设计软件;最后设计并完成了目标SAR数据库获取试验。相关研究在试验中得到了验证,并通过试验建立了军用卡车、通信车和坦克等多类目标多姿态SAR数据库,为SAR目标分类和识别技术研究提供了支撑,对其他军用目标SAR数据库的建立具有重要指导意义。Target SAR （Synthetic Aperture Radar） database is the foundation for study of target attributes identifi- cation and extraction. As the key of target SAR database experiment acquisition is ground target collocation and de- sign of the SAR carrier flight course, configuration requirements for range spacing and angle spacing of ground tar- gets are first studied. SAR carrier flight course design theory is given, including the length of flight course, course angle spacing and design of the experimental flight course in imaging center rectangular coordinate system. Compu- ting method of flight course longitude, latitude and altitude parameters in geocentric inertial coordinate system is de- rived and automatic experimental flight course design software is developed. Finally, target SAR database acquisi- tion experiment is designed. The research results are verified in SAR experiments. Meanwhile, multi-attitude SAR database of multi-class targets including military trucks, communication vans and tanks, is established based on the X band airborne SAR system. The results provide support to research on SAR target categorization and identification and have a high value for reference to building of SAR database for other military targets.
