Description
Technical field
The present invention relates to one of satellite communication antena technical field compact linear polarization tracker is and in particular to one kind
Compact conformation, the Waveguide polarization tracker for realizing mobile vehicle satellite communication antena passive line polarization tracking.
Background technology
With the development of communication technology of satellite, the application day of the mobile vehicle satellite communication antena such as vehicle-mounted, airborne or boat-carrying
Benefit is extensively.Satellite communication antena moved with the mobile vehicle moment, due to immobilizing of satellite antenna linear polarization angle, in order to ensure
During satellite communication antena linear polarization receiving and transmitting signal, antenna polarization angle is mated with the polarizing angle of satellite antenna all the time, it is to avoid
Because the energy loss that polarization adaptation causes is it is desirable to satellite communication antena linear polarization angle can rotate at any time, compensate due to carrying
The polarisation angles that body movement brings change relatively.
In Practical Project, for reflector antenna, typically realize linear polarization tracking by rotating linear polarization feed network,
But for the flat plate array antenna being widely used at present, said method obviously has no way of implementing, for circular or sub-circular
Flat plate array antenna, can realize linear polarization tracking by rotating whole flat plate array, but whole antenna structure will be extremely complex；
For the flat plate array antenna with certain length-width ratio, rotating the change spatially that whole flat plate array causes obviously cannot be by
Accept, so design can be used for carrier satellite communication antena, the linear polarization tracks of device of particularly flat plate array antenna becomes
The key of restriction associated antenna polarisation development.
Currently, linear polarization follows the tracks of mainly active and passive two kinds of implementations.Active linear polarization is followed the tracks of, and principle is simple,
The tracking time is short, but only enables for the tracking receiving frequency range linear polarization signal, and the key such as system standing wave, isolation refers to
Mark directly cannot be tested by instrument, passive line polarization tracking, and particularly waveguide wire polarization tracking device is because it docks sending and receiving
The features such as universality of radio band and low-loss, high-power, testability, gradually replace based on active linear polarization follows the tracks of into
Stream.

" rotor " realizes the tracking of linear polarization, and the transition coupling bandwidth of coaxial line to Wave guide system is narrower, and power capacity is not
Greatly.Secondly, this invention achieves orthomode coupler public affairs by the method that change waveguide broadside size changes waveguide wavelength
Phase equalization problem between port and two independent orthogonal ports altogether, however as the broadening of bandwidth of operation, this means
Affected by waveguide phase dispersion effect, bandwidth is wider, and dispersion is bigger, and phase contrast is bigger.Problem the most fatal is, in reality
Find in engineer applied, even if the phase contrast of the two of the orthomode coupler of foregoing invention output ports obtains very well, if in
When the phase contrast of its two port of flat plate array antenna connecting is larger, equally can be in polarization tracking device cavity underexcitation contrapolarization
Signal is although energy is very weak, but if contrapolarization signal can not be absorbed, the impact bringing is, in the process of polarization tracking
In, the angle of different frequency polarization tracking device rotations is different, and for certain satellite repeater antenna, whole work frequency
In band, the polarizing angle of all frequencies is changeless, and this is by the design difficulty that polarization tracking device servosystem is significantly greatly increased simultaneously
Impact communication efficiency.
