星载SAR系统应用领域不断扩展,应用需求也越来越多样化,研制满足特定应用需求的低成本轻小型SAR系统成为星载SAR系统发展热点。文中在介绍星载SAR发展现状和代表性轻小型SAR的基础上,针对轻小型SAR系统发展的几个方面进行探讨:均衡化设计发展策略、满足特定需求的低复杂度载荷、模块化快速响应系统以及星座和编队发展趋势、多体制并行技术路线等。结合典型轻小型SAR系统,在探讨发展的同时比较了不同体制轻小型SAR系统的技术途径、技术特点和应用方向。

With the enlarging application field of the space-borne SAR system, its requirement becomes more and more complicated.Hence, it is more important to develop a low budget light-SAR for specified need. In this paper, the development of spaceborne light-SAR for small satellite is summarized based on the development status of spaceborne SAR and representative light-SAR, including balanced development strategy, low complexity load, modular rapid response system and satellite networking, multi-system parallel technology route, et al. Combined with typical light SAR systems, the key techniques, character, application and performances of different systems are analyzed and compared.
