小卫星平台图像处理系统的可重构实现

摘要

With the development of small satellite technology, the requirements for satellite payload weight and volume increase stringently, and the functional mission is getting more and more complex. A small satellite image processing 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, low power 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.%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。
