雷达发射机在线监测系统设计

Design for On-line Monitoring System of Radar Transmitter

针对由于雷达元器件、部组件和关重件老化以及环境因素影响等,造成雷达探测距离下降,严重时会导致雷达工作异常,甚至发射机损坏的问题,设计了雷达装备发射机在线监测系统。该系统采用嵌入式Linux操作系统,以PC/104总线CPU模块为核心,由在线监测专用虚拟仪器模块和监测软件组成。结果表明:该监测系统能完成雷达发射机功率和天馈线系统驻波系数的在线监测,在监测精度、监测方法和可靠性等方面都优于以前的设备。目前该监测系统已成功应用于某型雷达整机性能监测系统中,并且取得了良好的效果。

Aimed at the problem of the loss of radar detection range and even the damage of transmitter due to the reasons such as environmental factors, aging effects including electronic components, critical parts and so on, the radar transmitter on-line monitoring system is designed. The monitoring system based on embedded Linux operating system is composed of virtual-instrument module and monitoring software, and the core of monitoring system is CPU module based on PC/104 bus. A series of researches show that this system can complete the on-line monitoring including radar equipment transmitter and standing wave coefficient of radar antenna feeder system. It also has many excellence superior to former instrument, including monitoring precision, monitoring method, reliability and so on. It has been successfully used for one type integrated performance monitoring system and proves fine through its outcome.
