摘要
近年来,伴随着卫星规模化应用热潮兴起,微小型SAR卫星迅速发展,成为空间遥感领域的新热点。文章系统梳理了国外典型微小型SAR卫星的最新发展情况,从单星规模、频段选择、工作体制、图像性能、星座构建等多个维度系统总结了当前微小SAR卫星技术发展水平;通过与国外大中型SAR卫星比较,分析微小型SAR卫星的应用场景和体系定位;最后,结合国内微小型SAR卫星发展现状,提出我国微小型SAR卫星发展的星座构建技术路线、轻小型技术的攻关方向和网络化、智能化体系的应用建议。
In recent years,with the upsurge of large-scale satellite applications,micro SAR satellites have developed rapidly and become a new hot spot in the field of space remote sensing.In this paper,we first systematically combs the latest development of typical foreign micro SAR satellites,and systematically summarizes the current development level of micro SAR satellite technology in several dimensions,including single satellite scale,frequency band selection,working system,image performance,constellation construction,etc.By comparing with foreign large and medium-sized SAR satellites,the application scene and system positioning of micro SAR satellites are analyzed.Finally,combined with the development status of domestic micro SAR satellites,the technical route of constellation construction of micro SAR satellites in China,the research direction of light-weight and miniaturization technology and the application suggestions of network and intelligent system are put forward.
