Embodiment Construction

[0024] The present invention is a terahertz wireless transceiver system used for measurement and control communication in the black barrier area. The scenarios used are as follows: figure 1 shown. When the aircraft flies in the atmosphere, the plasma sheath will cover the surface and surroundings of the aircraft, hindering the signal transmission of traditional measurement and control systems. Since this system works in the terahertz frequency band higher than 300GHz, when the transceiver system is used on the aircraft, since the working terahertz frequency band is significantly higher than the cut-off frequency of the plasma sheath, it can effectively reduce or eliminate the impact of the plasma sheath on the measurement and control signal. Absorption, to achieve the penetrating ability of the measurement and control signal to the three-dimensional sheath.

[0025] The working frequency band of this system is above 300GHz. Such as figure 2 As shown, the terahertz wireless...

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...
