摘要
星载SAR-GMTI系统具有地面(海面)大面积侦察、监视和运动目标检测、跟踪、定位的能力,是航天侦察的重要手段之一,可以为战场指挥、精确打击、态势评估提供高质量的情报信息。主要讨论星载SAR-GMTI系统及其研究进展,简述了国内外研究、发展现状,分析了现有的星载SAR/GMTI系统的优缺点和关键技术,探讨了星载SAR-GMTI系统所面临的技术挑战和研究重点。
Spacebome SAR-GMTI Systems have the ability to detect, track and relocate moving targets of the ground or the sea. The systems may provide high quality information for battlefield command, pinpoint strike and state evaluation, which is an important tech-nique for space based reconnaissance. In this paper, Spacebome SAR-GMTI Systems and relevant research process are introduced. The significant researches and development status quo in this field are discussed, and their limitations and key techniques are analyzed. Finally, the technique challenge and research emphasis are proposed.
