Description
Technical field
The utility model is related to microwave communication, star ground a kind of stent in communication in moving field more particularly to a kind of secondary reflections
Part mounting bracket.
Background technology
It is the antenna that critical piece forms by metal mirror and feed, mainly includes single reflection surface antenna and double-reflecting face
Two major class of antenna, this is based on antenna form derived from optical principle, is widely used in microwave and the shorter wave band of wavelength.Second
A variety of single reflection surface antennas start largely to use before and after world war, occur to the sixties using Cassegrain antenna as representative
Dual reflector antenna.They have become most common a kind of microwave and millimeter wave high-gain aerial, are widely used in communication, thunder
Reach, radionavigation, electronic countermeasure, telemetering, the technical fields such as radio astronomy and meteorology.By taking satellite communication as an example, due to gain
High and simple in structure, reflector antenna is the principal antenna form of communication satellite earth station；Since extensible folding umbrella can be made
Shape structure, it is the citation form of spaceship and satellite antenna again.So far diversified reflecting surface shape has not only been produced
Formula meets different needs, while a variety of feed structures of function admirable also occur.
Communication in moving is the abbreviation of " ground satellite station communication system on the move ".Star " communication in moving " be to meet user
The new opplication that the demand of broadband video information generates is transmitted in dynamic mobile by satellite, uses the Ku frequencies of trapped orbit satellite
Duan Jinhang mobile communication transmission wide-band-messages are a kind of emerging service applications.Pass through communication in moving system, vehicle, steamer, aircraft etc.
Mobile carrier during the motion can the platforms such as real-time tracking satellite, transmit the multimedias such as voice, data, image incessantly
Information can meet the needs of various military-civil emergency communications and the multimedia communication under mobile condition.
At present, " communication in moving " system is mainly communicated using Ku wave bands with trapped orbit satellite.According to 2014 national
Publication《The static middle onboard satellite communication earth station generic specifications used of Ku frequency ranges》、《Ku frequency range portable satellites lead to
Believe earth station generic specifications》Wait documentation requirements, Ku wave bands " communication in moving " system need to by application subsystem, power subsystem,
The compositions such as channel subsystem, antenna and its control system.Antenna system need to cover uplink/downlink frequency range simultaneously, wherein upper line frequency
Section is 13.75~14.5GHz, 10.95~11.75GHz of band downlink, 12.25~12.75GHz, the pole of uplink and downlink frequency range
Turn to two orthogonal linear polarizations.To ensure communication smooth between satellite and earth moving equipment, system antenna need to be directed toward logical in real time
Believe satellite.To the interference of neighbouring satellite when emitting in order to avoid antenna, it usually needs the tracking of mobile equipment antenna during exercise
Error is less than 0.1 °, and feed will also carry out rotation tracking, and the polarization isolation received between transmitting is greater than 30dB.This
Outside, corresponding requirement also proposed to the transmission power of antenna, minor level etc. in file.
At present, existing many enterprises unit is proposed " communication in moving " relevant product both at home and abroad, such as Israel RaySat public affairs
Multigroup chip antenna of department's release, the IMVS450M products of U.S. TracStar releases, Starling companies of Israel release
0.5m and the vehicle-mounted ring-focus antennas of 1.2m that Mijet series of products and Zhong electricity groups 54 of the country are researched and developed etc..To meet antenna pair
The requirement of the high-precision real-time tracking alignment of satellite, includes automatic tracking system in above-mentioned " communication in moving " product." in dynamic
It is logical " automatic tracking system is in initial static, course angle, carrier are measured by GPS, theodolite, Strapdown Inertial Navigation System
The longitude and latitude of position and the initial angle of relative level, then according to its posture and geographical location, satellite longitude certainly
The dynamic antenna elevation angle determined on the basis of horizontal plane, the rotational orientation under the premise of the holding elevation angle is constant to horizontal plane, and with letter
Number maximum mode is automatically aligned to satellite.During carrier movement, the variation of attitude of carrier is measured, passes through mathematical platform
Operation is transformed to the error angle of antenna, and antenna azimuth, pitch angle, polarizing angle are adjusted by servo mechanism, ensures that carrier is becoming
Antenna makes satellite transmitting antenna real-time tracking geostationary satellite in carrier movement to star in prescribed limit during change.
The system tracking mode has autotracking and inertial navigation to track two kinds.Autotracking be by satellite beacon carry out antenna closed servo with
Track；Inertial navigation tracking is to carry out antenna tracking using the variation of gyro inertial navigation combination sensitive carrier.Both tracking can be according to scene
Situation automatically switches.After system, which finishes star, to be transferred to from motion tracking, worked in a manner of autotracking；At the same time, inertial navigation system
Also enter working condition, and constantly export the data such as antenna polarization, orientation and pitching.When block or it is other due to cause day
When line beacon signal is interrupted, system automatically switches to inertial navigation tracking mode.
No matter antenna is using which kind of tracking mode, and high-precision servo-drive system is the key that traditional " communication in moving " system always
One of part.Under normal conditions, high accuracy servo system need to have about 0.1 ° of high tracking accuracy, simultaneously because " communication in moving " day
Line has larger bore (meeting the antenna aperture for the requirement that networks at present more than 1 meter) and weight, is watched so as to cause high-precision
The higher cost of dress system.At present, high accuracy servo system cost applied to " communication in moving " is tens thousand of easily, even more than ten
Ten thousand, entire " communication in moving " system cost most is accounted for, it is extensive in civil field to limit " communication in moving " communication system
