摘要
星载测控天线是每颗卫星必备的设备之一,其方向图的设计不仅要考虑正常运行时的测控通信需要,也要保证卫星姿态异常情况下能够与地面进行测控通信,因此星载测控天线往往通过几副天线的合成来达到方向图的准全向,但合成部位存在干涉区,此干涉区在某些情况下会影响正常的测控通信.主要阐述通过对天和对地分配能量的调整,以及对天和对地天线的合理布局和设计来调整干涉区的位置,从而满足不同卫星的使用要求.
Abstract
Measurement and control spaceborne antenna is one of necessary equipments in a satellite. The design of antenna pattern should be satisfied with the requirement of communication of measurement and control system not only at normal case but also when the attitude of the satellite is abnormal. So the omni-direction of antenna pattern is generally obtained by combining several antennas. But there' s interference areas in the part of combination which will effect the normal communication of measurement and control system. This paper presents a method to solve this problem which can adjust the position of interference ares by rational layout and reasonable distribution of the power between the sky-forward and the land-forward antennas to satisfy the requirements of all kinds of satellites.
