卫星数传分系统通用地检测试中频接收机设计

Design of General Ground Integrated Test Intermediate Frequency Receiver for Satellite Transmission System

为满足卫星数传分系统测试任务需求,提出一种通用性、灵活性强的地检测试中频接收机设计方案.采用软件无线电设计思想,设计基于PXIe总线的模块化平台,通过FPGA进行硬件实现,符合CCSDS标准.经过工程实践,所提出的地检测试中频接收机方案已应用于工程型号,并成功执行各阶段测试工作.

In order to meet the task requirement of the integrated ground test for the satellite transmission system, the ground integrated test IF （Intermediate Frequency） receiver with strong generality and flexibility is designed. Based on the modularized platform with PXIe bus to exchange the information and command between the receiver and the monitor, the idea of software radio frequency is adopted to realize muti-mode system in this design, and the algorithm is implemented through FPGA according to the CCSDS standard. The design proposed in the paper has been already applied to some satellite projects, and successfully implement the task of test in each phase of the mission.
