Novel polarization tracker

Abstract

The invention relates to a novel polarization tracker, belonging to the technical field of polarization tracking. The novel polarization tracker is mainly composed of four parts including an orthogonal mode coupler, a general signal input or output interface, a rotary rotor and a motor. The motor of the novel polarization tracker drives the rotary rotor to rotate in 360 DEG; and polarization matching is realized till a maximal signal pointing direction is tracked in a polarizing manner. The novel polarization tracker disclosed by the invention has the outstanding advantages that: signals are accurately tracked in the polarizing manner; the novel polarization tracker can be used as a receiving polarization tracker used for synthesizing two signals from two parallel ports and receiving required signals in the polarizing direction through rotation of the rotary rotor; and furthermore, the novel polarization tracker can be used as a transmitting polarization tracker used for receiving a satellite polarization signal through polarization tracking and transmitting by dividing the satellite polarization signal into two signals through the orthogonal mode coupler in the polarization tracker. According to the invention, the disadvantage of non-parallel output of two output arms of the existing polarization tracker can be solved; and furthermore, the novel polarization tracker disclosed by the invention is simple in structure, convenient to cascade and easier to process.

Description

technical field [0001] The invention relates to a novel polarization tracker, which can be used alone as a microwave circuit device, and can also be applied to a "communication in motion" system, belonging to the technical field of polarization tracking. Background technique [0002] As an important component to realize dual-polarization antenna feeder, polarization tracker is widely used in satellite communication and military radar. The two input ports of the existing polarization tracker are usually two standard rectangular waveguide ports perpendicular to each other. This design adjusts the size of the standard rectangular waveguide output port, although it is easy to achieve the same physical path of the two signals to ensure the output phase unanimous. However, the shortcomings are also obvious: in practical engineering applications, the two output ports perpendicular to each other still need to be connected to the two parallel rectangular waveguide ports of the duple...
