微波着陆系统天线模拟器的设计与实现

为降低微波着陆系统(MLS)的在线检测与维修成本,改善系统测试的工作环境,增加天线系统使用寿命,基于嵌入式控制系统ARM技术与可编程门阵列FPGA技术设计并实现了一种实用的MLS天线模拟器.该模拟器可产生六付天线射频序列检波信号和环境监测信号,具备环境告警能力.实测结果表明:模拟器产生的天线模拟信号能够满足MLS的系统要求,且与设备主机有很好的兼容性,所有模拟信号均可作为监测信号回传至MLS设备主机,用以保证设备正常工作,为MLS系统检测提供了一种新的平台.

The Design and Implement of MLS Antennas Simulator

In order to cut down the cost of the detecting and repairing of MLS online ,improve the environment of systems test and increase the life-span of antennas system, the technology of ARM and FPGA have been adopted to complete the design of a practicality MLS antennas simulator. The device has simulated radio-detected signals of six antennas, environment monitoring signals, and has the ability of environment warning. As monitored signals, all the signals head back to MLS mainframe so as to the MLS devices can work up to snuff. And it provide a new bench in the monitoring of MLS.
