摘　　要：根据再入遥测技术的特征,再入遥测系统应具备实时信号处理的能力和切换工作模式的能力。文中用FPGA控制数据通道,选择PCI作为再入遥测系统与计算机的接口,用浮点DSP实现信号的实时处理。经过仿真测试,该方法符合再入遥测系统的要求。According to the characteristic of the reentry telemetry technology,the reentry telemetry system is required to have the ability to process real time signal and switch between the two modes.In this paper,FPGA is used to control the data access,PCI interface is selected in this system to communicate with the computer,and floating-point DSP is used to process the real time signal.The simulation result proves that this method is acceptable for the reentry telemetry real time signal processing system.
