摘要
本文叙述了日像仪实验的方案,双天线干涉仪中模拟接收机的结构,灵敏度,动态范围,噪声,增益的各级分配等问题,基于实验方案设计了日像仪模拟接收机。
The analogy receiver structure of CSRH experiment-two elements interferometer is presented in this paper. The sensitivity, dynamic range, noise figure and gain distribution of the instrument are discussed. The analogy receiver for CSRH is designed on experiment result.
