天体角度射电测量装置的设计与试验

Design and Test of Radio Celestial Body Angle Measurement Set

介绍了天体角度射电信标电磁波辐射特性和射电测量装置的组成,研究并选择了射电信标跟踪测量模式,进行了圆锥扫描天线系统设计,完成了接收机系统设计及灵敏度计算。在此基础上,进行了测天试验,实测结果表明:天体角度测量装置的最高测角精度达到了5.2″,最差测角精度不超过29.7″。

The make up of celestial body angle measurement set of celestial body and the characteristics of radio beacons＇ electromagnetic wave radiation are introduced. The mode of radio beacons＇ trace and measurement is researched. Taper scan antenna system are designed, and the design and sensitivity calculation of receiver system are achieved. On the base of all above, experiments of celestial body angle measurement are done. The test results show that the highest precision of angle measurement reaches 5.2＂ and the lowest precision does not exceed 29.7＂.
