摘要
详细汇总了国内太阳射电望远镜的技术性能及原理框图。收集了部分国外太阳射电望远镜技术指标。对射电望远镜系统参数灵敏度、信噪比、交叉计划隔离度的计算方法作了介绍。
This paper lists in details the technical parameters and block diagrams of solar radio spectrographs in China and abroad.The paper also lists technical specifications of some solar radio telescopes abroad.In addition,we describe the analysis method of some key specifications,which are signal-to-noise ratios,dynamic ranges,and cross polarization isolation.The description includes formulas of these specifications in an example case.
