星载相控阵天线的技术现状及发展趋势

内容简介：星载相控阵天线采用现代微波集成技术，在有限的卫星平台空间条件下，实现独立控制的多个点波束，满足未来通信的需求。相控阵天线可以实现波束间通信容量的调整，还可以根据需要改变波束形状，使用自适应调零的抗干扰技术，这些技术已在国外星上设备中广泛采用，具有广阔的发展前景。文章介绍了星载相控阵天线的研究现状、关键技术，以及发展趋势，并对我国星载相控阵天线技术的发展提出了建议。

Abstract：Satellite phased array with modern microwave integrated circuit technology takes limit space on satellite and is able to independently control many beams to satisfy the demands ofmod- ern communication. The power ration between beams of phased array is adjustble. The radiation beam shape is variable and adaptive anti-jamming technology is easy to apply. Satellite phased ar- ray has been applied in wide domain and has increasing developing future. This paper gives the research status of satellite phased array, the key technologies and prospects the developing trends of satellite phased array.
