System for realizing integration of terahertz tracking and data relay communication

Abstract

The invention discloses a system for realizing integration of terahertz tracking and data relay communication. The communication subsystem comprises a duplexer, a receiving subsystem and a transmitting subsystem, signals received by a terahertz antenna are restored into information signals through the duplexer and the receiving subsystem, or the information signals pass through the transmitting subsystem and the duplexer and are radiated to a free space through the terahertz antenna; the antenna and tracking and pointing subsystem captures, tracks and aims at the signals; and the auxiliary function subsystem receives an instruction for establishing a communication link and related parameters through the telemetering and remote control module, outputs the telemetering parameters, and switches the working modes of the terahertz communication terminal. According to the system, the integration of terahertz tracking and data relay communication is realized by utilizing the spatial transmission and high bandwidth characteristics of a terahertz waveband and combining a baseband high-speed modulation and demodulation technology, and the application requirements of tracking and data relay communication in near space anti-blackout communication and high-speed data transmission can be met.
