A kind of inter-satellite Terahertz communication system framework and its information transferring method

The invention discloses a kind of inter-satellite Terahertz communication system frameworks, and including the transmitter and receiver being arranged on satellite platform, when Terahertz frequency range is the low-frequency range less than 10THz, the transmitter uses flood tide Terahertz antenna array；When high band of the Terahertz frequency range in 10THz~30THz, the transmitter is thz laser device；When Terahertz frequency range is above-mentioned low-frequency range or high band, the receiver is flood tide Terahertz antenna array；The flood tide Terahertz antenna array includes 10 4 ~10 7 The bay of the order of magnitude, the flood tide Terahertz antenna array are made using semiconductor technology, and the bay by several work in different wave length is realized using the same technique, to realize multi-frequency MIMO system；The receiver will extract information after receiving THz wave by a detection quantum device, and drive the same detection quantum device using several bays.Present system framework has merged the advantages of infrared laser communication and millimetre-wave attenuator.
