摘　　要：为了满足卫星地面站和测试站相距数百公里部署场景下进行地面链路指标测试、卫星在轨测试、任务阶段频谱监视等多任务在轨测试需求,对传统在轨测试系统进行了设计改进,提出了一种基于柔性测试网络的测试系统构建思路.提出了利用等幅多载波群时延测量方法进行异地群时延测量;设计了光传输链路替代传统波导的微波信号传输链路,并进行了可行性试验;构建了可自动切换满足各阶段各类别测试项目并行测试的柔性测试网络;测试软件的服务端采用面向服务的软件架构,测试客户端采用平台加插件架构,实现了测试系统设备可定义、任务可并发、流程可定制的能力.In the deployment scenario where the satellite ground station and the test station are hundreds of kilometers apart,in order to meet the requirements of multi-task in-orbit tests such as ground link index test,satellite in-orbit test,satellite frequency spectrum monitoring during the mission phase,the design of in-orbit test system is improved,and a construction idea of test system based on flexible test network is proposed.An equal amplitude multicarrier group delay measurement method for remote group delay measurement is proposed.The optical transmission link is designed to replace the waveguide transmission link,and the feasibility is verified.A flexible test network that can automatically switch to meet the requirement of parallel tests and various stages and categories of test projects is constructed.The server of test software adopts the service-oriented software architecture,and the client adopts the platform plug-in architecture to realize the ability that the test system devices can be defined,tasks can be concurrent,and processes can be customized.
