Embodiment Construction

[0069] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0070] The basic idea of ​​the invention is: a novel polarization tracker, which belongs to the technical field of polarization tracking. The new polarization tracker mainly consists of four parts: a quadrature mode coupler, a signal input (or output) main port, a rotating rotor and a motor. The motor of the polarization tracker drives the rotating rotor to rotate 360°, and the polarization is tracked to the direction of the largest signal to achieve polarization matching. The outstanding advantage of the present invention: accurate polarization tracking of signals can be used as a receiving polarization tracker to synthesize two signals entering from two parallel ports, and receive the required polarization direction by rotating the rotor signal; it can also be used as a transmitting polarization tracker, which receives satellite polarizati...

Abstract

The invention relates to a novel polarization tracker, belonging to the technical field of polarization tracking. The new polarization tracker mainly consists of four parts: a quadrature mode coupler, a signal input or output port, a rotating rotor and a motor. The motor of the new polarization tracker drives the rotating rotor to rotate 360°, and the polarization is tracked to the direction of the largest signal to achieve polarization matching. The outstanding advantage of the present invention: accurate polarization tracking of signals can be used as a receiving polarization tracker, which synthesizes two signals entering from two parallel ports, and receives the required polarization direction by rotating the rotor It can also be used as a transmitting polarization tracker, which receives satellite polarization signals through polarization tracking, and then divides them into two signals and transmits them through the orthogonal mode coupler in the polarization tracker. The invention solves the shortcoming that the two output arms of the current polarization tracker do not output in parallel, and the invention has simple structure, convenient cascade connection and easier processing.

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...
