Abstract

The invention discloses a vehicle-mounted communication-in-motion polarized tracking adjusting apparatus. A polarized rotation shaft is mounted on a polarized tracking adjusting apparatus mounting bracket; the polarized rotation shaft comprises transmission waveguide; one end of the transmission waveguide is connected with a feed source loudspeaker while the other end of the transmission waveguide is assembled with a polarized transmission gear; the transmission waveguide is assembled with a sleeve; a bearing is arranged between the transmission waveguide and the sleeve; the sleeve and the polarized tracking adjusting apparatus mounting bracket are fixedly connected; the outside of the polarized transmission gear is connected with an antenna polarization driving system; an orthogonal mode coupler is connected with a Ku frequency band microwave rotary joint, and fixed on back end waveguide; the back end waveguide is connected with the polarized tracking adjusting apparatus mounting bracket; and the polarized tracking adjusting apparatus mounting bracket is also provided with a transmission apparatus. The apparatus has the characteristics of high positioning precision, compact structure, and high reliability and maintainability; polarization matching requirement of polarization tracking in high-speed and high-acceleration states can be satisfied; and degradation of performance of a transmission channel caused by polarization mismatching can be avoided.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a vehicle-mounted communication polarization tracking adjustment device. Background technique [0002] The vehicle-mounted "Mobile Communication" is a vehicle-mounted station that can carry out uninterrupted satellite communication while moving. "Mobile communication" can be widely used in battlefield military communications, helicopters, unmanned aerial vehicles, remote communications of early warning aircraft, mobile command, anti-terrorism emergency communications, geological surveys, flood and fire disaster site emergency communications, live broadcast of competitions, real-time news collection and Fields such as telemetry and remote sensing of weather and meteorology can transmit information in real time, with large capacity, uninterrupted and stable. [0003] The key technology of the mobile communication is mainly the intelligent tracking technology, that ...
