摘要
讨论了Ka频段地球网测控通信的特点和主要技术问题,指出了它在高速数传、抗干扰、提高作用距离、提高测量精度、减小"黑障"影响、兼容Ka频段卫通等方面的优点,提出了用虚拟测控系统解决雨衰,用空间谱分析解决Ka频段窄波束捕获等的方案设想。
This paper discusses the characteristics and key technical problems of Ka -band earth TT＆C communication network, points out the advantages of TT＆C communication network in high speed data transmission, anti - jamming, increasing operation distance, improving measurement precision, reducing effect of blackout and Ka - bandsatellite communication compatibility, etc. , then proposes the assumption that the virtual TT＆C system be used to solve the rain -fade, and the space spectrum analysis be used to solve Ka- band narrow beam acquisition.
