雷达接收机故障诊断辅助系统的设计研究

为了提高雷达接收机故障诊断的速度和精度，快速准确地排除接收机故障，设计出雷达接收机离线故障诊断辅助系统。该系统使用嵌入式微处理器智能控制，结合大规模集成电路现场可编程门阵列（FPGA），可产生模拟雷达中频回波信号，使雷达接收机在仿真环境中工作，以便于维修人员进行故障检测分析。该系统已经应用于某型雷达检测仪。

Research into The Design of Fault Diagnosis Auxliary System for Radar Receiver

In order to raise the speed and the precision of fault diagnosis for radar receiver and remove the diagnosis of the receiver fast and accurately,this paper designs an auxiliary system of offline fault diagnosis for radar receiver. The system uses inserted microprocessor to perform intelli- gence control, can simulate radar intermediate frequency （IF） echo signal combining with large scale integrated circuit field programmable gate array （FPGA）,which makes radar receiver operate in simulative environment and this is easy for serviceman to carry on the check and analysis to fault. This system has been applied to an radar checkout instrument.
