摘　　要：随着小卫星技术的发展,对卫星载荷的质量体积要求日益苛刻,而功能使命却日益复杂,提出了以系统重构技术为基础,针对高功能密度、高性能的小卫星图像处理系统。设计了一种体积小、质量轻、响应速度快、功耗低、可靠性高的图像处理系统可重构平台,实现了针对不同任务阶段不同种类图像处理的快速切换,并通过冗余设计保证了系统的稳定运行,满足空间环境工作需要。With the development of small satellite technology, the requirements for satellite payload weight andvolume increase stringently, and the functional mission is getting more and more complex. A small satellite imageprocessing system for high function density and performance based on system reconfiguration technology is pro-posed. An image processing system reconfigurable platform with small size, light weight, fast response speed, lowpower consumption and high reliability is designed to realize fast switching among different images at different mis-sion stages. And system stable operation is ensured through redundant design to meet the requirements of space op-eration environment.
