ADS-B接收机自动测试系统的设计与实现

Design and Implementation of an Automatic Test System for ADS-B Receivers

为实现广播式自动相关监视(ADS-B)接收机性能参数自动测试,开发设计了ADS-B接收机的自动测试系统。系统由ADS-B射频信号生成和上位机组成,采用了现场可编程门阵列(FPGA)和单片机MSP430实现ADS-B射频信号的生成;采用C#语言编写上位机程序,实现了对接收机灵敏度和接收机带宽等关键技术指标的自动测试。最后,搭建了某款ADS-B接收机的测试系统。测试结果表明,该系统测试效率高,运行稳定且易操作,可满足对ADS-B接收机的性能测试与故障检查需要。

In order to implement automatic test of performance parameters for the Automatic Dependent Surveillance-Broadcast(ADS-B)receiver,an automatic test system is designed and developed.The system is composed of ADS-B RF signal generator and host computer.Based on Field Programmable Gate Array(FP-GA)and single chip microcomputer MSP430,the part of ADS-B RF signal generation is realized.The soft-ware for host computer is written in C#language.The developed system can automatically test the key technical parameters such as the sensitivity and bandwidth of the receiver.Finally,an automatic test system for an ADS-B receiver is built.The test results show that the system is featured by high test efficiency,stable operation and easy operation,and can meet the needs of the performance test and fault diagnosis requirements for ADS-B receivers.
