Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to figure 1 , figure 2 , is a schematic diagram of a dual-channel duplex polarization tracker of the present invention.

[0024] The two-way duplexer 2 includes two signal transmitting end filters, two signal receiving end filters, and two E-T connectors 15, and the output end of the signal transmitting end filter and the input end of the signal receiving end filter pass through E-T The two symmetrical interfaces of the connector 15 are connected in one-to-one correspondence; the spare interfaces of the two E-T connectors 15 are used as two signal receiving and receiving interfaces.

[0025] When the spare interface of one of the E-T connectors 15 receives satellite signals, the spare interface of the other E-T connector 15 transmits microwave signals. The two-way duplexer 2 can realize simultaneous reception and transmission...

Abstract

The invention belongs to the satellite communication technical field and discloses a dual-channel duplexer and a dual-channel and duplex polarization tracker using the same. The dual-channel and duplex polarization tracker comprises an emission polarization tracker used for performing polarization adjustment on emitted signals so as to make the emitted signals match and track satellite signals; the emission polarization tracker is provided with an output end and an input end; the output end of the emission polarization tracker is provided with a dual-channel duplexer used for separating emitted signals and received signals from each other; the dual-channel duplexer is provided with an input end, an output end and two transmitting-receiving ends; and the output end of the dual-channel duplexer is provided with a reception polarization tracker used for adjusting a polarization angle to make the polarization angle match and track received satellite signals. The polarization tracker has the advantages of low loss and high tracking accuracy. With the dual-channel duplexer and a dual-channel and the duplex polarization tracker using the same of the invention adopted, space occupied by a system can be decreased under the premise that the size of an antenna can be as small as possible, and the contour and height of the system can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of satellite communication, and in particular relates to a double-way duplexer and a double-way duplex polarization tracker using the double-way duplexer. Background technique [0002] Due to the widespread use of mobile satellite antennas in motion, mobile carriers such as automobiles, trains, ships, and airplanes can track communication satellites in real time, establish communication links, and transmit voice, data, and images without interruption. and other multimedia information. The system has the advantages of wide communication coverage area, no terrain and geographical restrictions, stable and reliable transmission lines, broadband transmission, and mobile communication. The "Mobile Communication" mobile satellite communication antenna system can greatly improve the user's communication capabilities during the movement process, so the system can meet the multimedia communication needs of various mi...
