基于RF开关矩阵的雷达双通道测试平台

Test Platform of Dual Channel Radar Based on RF Switch Matrix

雷达性能测试贯穿于雷达系统的研发和使用阶段,针对目前雷达测试平台存在集成化、稳定性不足的情况,设计了一种基于射频(RF)开关矩阵的雷达性能双通道集成测试平台;首先,基于RF开关矩阵和通用仪器设计双通道测试结构;继而开发程控软件,同步控制开关矩阵的切换和各项仪器的数据采集,实现自动化雷达性能测试;该平台校准面插损和测试面插损之间的误差远小于传统方法,对雷达指标的测试精度可达到0.1dB以上;且通过自动化的信号采集、信号处理及数据分析,实现了对雷达设备的高精度、高效率自动化性能测试。

The radar performance testing penetrates the development of radar system and using period.Aiming at the shortcoming of integration,stability in radar test platform,this paper designs a dual channel integrated test platform of radar performance based on the radio frequency （RF） of the switch matrix.First of all,the design of RF switch matrix and generalinstrument bases on dual channel test structure and then the development of programmable software,data acquisition and switching synchronization control switch matrix and various instruments,implementation of performance testing automation.The platform uses the analysis of signal acquisition,signal processing and data automation,achieving high precision,high efficiency automatic performance test of radar equipment.
