摘要

介绍了射电天文接收机的基本原理。研究了系统的噪声、温度、不同类型接收机的灵敏度以及接收机的标定。分析了一种全功率接收机作为基本的射电望远镜接收机。将所得结果用于其他类型接收机的性能分析,如Dicke接收机、Graham接收机、相关接收机和相开关接收机。

Radio Astronomy Receivers
A general survey of the principles of radio astronomy receivers is presented. System noise temperature, the sensitivity of different receiver types, and the calibration of receivers are studied. A total-power receiver is analyzed as a basic radio telescope receiver and. the results are used to obtain the performance of other receiver types such as the Dicke receiver, Graham's receiver, correlation receiver, and phase-switching receiver.
