A terahertz wireless transceiver system for black barrier area measurement and control communication

Abstract

The invention discloses a terahertz wireless transceiver system for black barrier area measurement and control communication, the system including a transmitting part, a receiving part, a circulator,an antenna feed system and an analog cancellation circuit. The annulator and the analog cancellation circuit are arranged between the transmitting part and the receiving part. The annulator is connected with the antenna feed system. The transmitting part sends the transmitted radio frequency signal into the annulator, radiates to the space through the antenna feed system, and part of the transmitted radio frequency signal coupled from the directional coupler at the end of the transmitting part enters the receiving part through the analog cancellation circuit. The system is installed on high-speed aircraft and works in the terahertz frequency band higher than 300 GHz. It can effectively reduce or eliminate the absorption of measurement and control signals by plasma sheath and achieve the penetration ability of the measurement and control signals to the stereoscopic sheath.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a terahertz wireless transceiver system for measurement and control communication in blackout areas. Background technique [0002] When the high-speed aircraft flies in the adjacent space, due to the intense friction and extrusion with the atmosphere, the surface temperature rises sharply to above 3,000 Kelvin, which causes the ionization of atmospheric molecules, so that the electrons orbiting the nucleus in the atmospheric molecules break away from the shackles of the nucleus and form a free space. electrons, atmospheric molecules that have lost electrons form positively charged ions. Free electrons and ions form a plasma on the surface of the vehicle. In addition, due to the ionization of the heat insulation material of the aircraft itself under high temperature ablation, the surrounding electron concentration increases significantly, forming a plasma with a certain thickn...

Problems solved by technology

The area where the black barrier phenomenon occurs when the aircraft flies in the adjacent space is called the "black barrier area". The traditional microwave measurement and control methods in the black barrier area cannot solve the problem of information transmission.
