有源相控阵天线自动测试系统设计

针对现代有源相控阵雷达天线T/R组件测试通路多、测试数据处理量大、测试效率低的特点,设计了一种适用于大规模T/R组件测试的有源相控阵天线自动测试系统。该系统设计通过GPIB接口或以太网对VNA(矢量网络分析仪)进行访问控制与数据采集,充分利用了现代计算机强大的数据处理与分析能力,不仅解决了有源相控阵天线故障诊断与自动校正问题,而且还极大地提高了工作效率,节约了人力成本。实际应用表明:该测试系统工作稳定,使用方便,能够充分满足T/R组件测试需要。

Design of Automatic Testing System for Active Phased Array Antenna

Aimed at multi-channel, large amount of testing data, low test efficiency in T/R module test of active phased array antenna, we designed an automatic test system for active phased array antenna, which adapts to testing large amount of T/R modules. The system controls VNA and gathers data from it via GPIB or ethernet and fully uses strong ability of modern computer for processing and analyzing data. It not only solves the problems of trouble diagnosis and automatic calibration of active phased array, but also improves the work efficiency and saves human cost. Results of actual application show that the test system works stab ly, and is easy to operate, it can meet the demands for measuring T/R module.
