中文摘要： 深空探测是空间信息网络的重要信息获取通道。随着探测距离越来越远，亟需进行在轨处理以提高深空通信的可靠性与稳定性。由于我国目前的星载天线水平及器件能力相对落后，深空通信在轨处理面临着微弱信号感知、大跨度多任务处理、恶劣辐照环境长周期生存等挑战。本项目面向我国深空通信长期可持续发展的需求，从星上信息感知方法、信息处理架构、承载平台演进等方面系统深入研究在轨处理关键技术，包括噪声辅助的微弱信号感知与接收方法、参数驱动的多体制通信可重构处理架构、具有自愈功能的在轨处理硬件演进系统等。通过本项目的研究，可突破制约我国深空通信发展的信息处理瓶颈和承载平台瓶颈，探索出利用商业CMOS工艺发展宇航级抗辐照芯片的新方法，为空间信息网络的高效传输奠定技术基础。

英文摘要： Deep space exploration is the important information source for space information network. As the distance is further, it is urgent to develop on-orbit processing to improve the reliability and stability of deep space communication. For the relative backward in the fields of satellite antennas and chips, there are many challenges to overcome, such as weak signal sensing, multiple widely different tasks processing, long time lifecycle platform under heavy radiation environment. In this project, we focus on the information sensing method, the processing structure, and the carrier platform, including weak signal sensing and receiving method with the aid of noise, multiple communication schemes reconstruct processing structure with the drive of parameters, on-orbit processing hardware evolution system with self-cure ability. With the project, we aim to break through the bottlenecks of information processing and carrier platform, form the new method of space grade chips with the commercial CMOS technology, which can improve the transmission efficiency significantly for space information network.
