针对微波暗室结构布局、性能和实际使用需求,设计一套天线远场测试系统,详细分析系统的射频分系统方案配置及其仪表选型,估算频带内测量系统的动态范围.实际应用表明该系统满足设计要求,具有适用频率范围宽、系统动态范围大、测量效率高等优点,可为类似系统的设计提供参考.
Based on the structural configuration and performance of a microwave dark chamber,as long as actual use demands,an antenna far-field test system is designed.A detailed analysis of the solution configuration of the RF subsystem and the selection of instruments is carried out,and the system dynamic range is calculated within the frequency band.The practical application shows that the system meets the needs of the design,with wide frequency range,large dynamic range,and high test efficiency,providing reference for designing similar systems.
