全数字化星载信号处理载荷架构设计

面对商业航天新业态的迅猛发展，围绕高可靠、高效率、高效益的航天发展目标，针对卫星有效载荷的载荷核心——星载信号处理载荷部分，参考美国国家航空航天局的空间无线电通信体制设计思路，以硬件平台化、功能软件化、软件构件化为特征基础，通过对软硬件体系、载荷时频、重构方式、资源共享等多元化的设计，构建了一种灵活、通用、易扩展、需求适应强的全数字化星载信号处理载荷架构。相比于传统星载信号处理载荷，采用该架构设计的星载信号处理载荷可以广泛适应各类星载信号处理的需求，极大地提升有效载荷的信号处理能力及可靠性，降低载荷的研制周期与成本，为未来卫星有效载荷的软件化、网络化、智能化发展提供技术支撑。

Design of fully digital spaceborne signal processing payload architecture

In the face of the rapid development of new commercial aerospace formats, focusing on the aerospace development goal of high reliability, high efficiency and high benefit, in view of the satellite payload part load core - satellite signal processing load, this paper refers to the design idea of NASA''s STRS system, based on the characteristics of hardware platform, software function, and software component, through the diversified design of hardware and software system, load time and frequency, reconstruction mode and resource sharing. A flexible, versatile, scalable and adaptable payload architecture for satellite-borne signal processing is constructed. Compared to traditional spaceborne signal processing load, the use of the architecture design of spaceborne signal processing load can be widely used to all kinds of spaceborne signal processing requirements, greatly improve the payload of the signal processing ability, and reliability, effectively reduced the load of the development cycle and cost, for the future satellite payload software, network and intelligent development to provide technical support.
