摘　　要：为了构建空间电场测量体系,设计了基于FPGA的星载电场仪信号处理系统。区别于探空火箭电场信号测量系统,星载电场仪系统采用Xilinx FPGA为主控制器和数据处理单元,同时针对星上环境提出了偏置电流源和浮动参考地等独特设计。文章介绍了系统的硬件设计和软件设计。测试结果表明,系统稳定可靠,具有一定的参考价值和实际应用价值。In order to construct the space electric filed measurement system, the paper presents a satellite-borne electric field signal processing system design based on FPGA. Differ from the sounding-rocket-borne electric field measurement system, it takes Xilinx FPGA as a main controller and data processing unit, and makes some unique designs for the satellite environment, including bias current source and floating ground. The paper introduces the hardware design and the software design of satellite-borne electric field signal processing system. The test results show that the design is reliable and has reference and practical value.
