摘　　要：星载综合射频系统安装在卫星或太空载具上,负责通信链路建立、数据传输、信号采集和处理等。随着卫星通信需求不断增强,该系统正持续发展演进。然而,传统的紧密耦合软硬件计算模式已不再适用。基于此,设计了一种星载综合射频系统软件定义平台,其旨在实现波形应用与底层平台的解耦。考虑到星载系统的特殊环境和资源限制,此设计致力于应对苛刻资源环境带来的轻量通信、动态任务重构及潜在的单粒子翻转问题。借助软件定义的手段,将计算任务与具体硬件解耦,同时实现任务模式的动态重构,可以更好地应对持续增长的计算需求。The starborne comprehensive RF system is installed on satellites or space vehicles and is responsible for tasks such as establishing communication links,transmitting data,and collecting and processing signals.As the demand for satellite communication continues to grow,the system is continuously evolving.However,the conventional tightly coupled software-hardware computing model is no longer applicable.In view of this,this paper designs a software-defined platform for starborne comprehensive RF system,which aims to decouple waveform applications from the underlying platform.Considering the unique environment and resource constraints of starborne system,this design strives to address challenges posed by stringent resource conditions,including lightweight communication,dynamic task reconfiguration,
