DJS-1 卫星平台测控天线

TT&C Antenna for DJS 1 Satellite Platform

介绍一种与ＤＪＳ－１卫星平台及我国卫星测控网适应的卫星测控天线。设计充分考虑三化要求，辐射单元采用能实现“轴向型”宽波束方向图的小口径喇叭，在卫星指地面和背地面各装一付天线，就可组成双向方向图。在喇叭后加一个正交模耦合器，就可实现正交辐射。从而初步实现卫星测控天线的模块化和通用化。

A TT&C antenna is described suitable for DJS 1 satellite platform and Chinese satellite TT&C stations.The requirements of generalization and modularization and seriation is sufficiently considered.The small aperture broad beam horn is adopted.So long as two antennas are assembled on the spacecraft's earth facing panel and sky facing panel,bidirectional pattern is made up of ;Using an OMT,orthoploarization radiation is realized.Thereby ,normalization and modularization is achieved.
