|
摘要
接收机系统是体现微波辐射计探测性能指标最关键的组件,本文阐述了地基微波辐射计集成式多接收机并行滤波接收系统的结构和技术特点,分析了其相较于单接收器变频技术的优点,进一步根据福州站的探测数据产品分析了该接收系统的实际应用效果,旨在为相关技术人员提供地基微波辐射计应用研究方面的技术参考。分析结果表明并行接收系统的应用提高了地基微波辐射计的探测性能。
The receiving system,which is called the parallel filter system with the integrated multireceiver,as the most critical component of the ground-based microwave radiometer,it is necessary to examine its structure and technical characteristics.The advantage,compared with the single receiver,i.e.,frequency conversion technology,is described and the actual application effectiveness of the receiving system is analyzed by means of radiation data and products.It is concluded that this receiving system can improve the detecting capability of the ground-based microwave radiometer.The findings can be used to provide reference for relevant technicians in the application and analysis of ground-based microwave radiometers.
