Problems solved by technology

[0002] In the prior art, the feeder system of satellite communication reflector in motion adopts Ku / Ka dual-frequency duplex program tracking or Ku / Ka dual-frequency duplex time-sharing switching monopulse self-tracking as the feed source, and the types of equipment required And the quantity is large, the overall complexity of the equipment is high, and it is prone to failure; but in effect, only Ku-band monopulse tracking or Ka-band monopulse tracking can be realized, and the self-tracking channel must be switched through the switch network, and it is not possible to perform simultaneous tracking. Simultaneous monopulse tracking capability of Ku-band and Ka-band
In addition, since Ku-band monopulse tracking or Ka-band monopulse tracking works independently, when the working Ku or Ka self-tracking channel fails to track, the other channel cannot complete the real-time tracking task, so the entire device easy to lose target

Abstract

The invention relates to a dual-frequency duplex full-simultaneous single-pulse self-tracking satellite communication feed source. The dual-frequency duplex full-simultaneous single-pulse self-tracking satellite communication feed source simultaneously has the functions of Ku-band uplink transmission, Ku-band downlink single-pulse self-tracking, Ka-band uplink transmission and Ka-band downlink single-pulse self-tracking for satellites. The feed source adopts a dual-band speaker (1), a Ku-band TE21 mode coupler (2), a Ka-band TE21 mode coupler (3), a six-port lantern splitter (4), a Ku-band orthogonal mode coupler (5) and a Ka-band circular polarizer (6); a Ku-band differential mode, a Ka-band differential mode, a ku-band sum mode and a Ka-band sum mode are separated in sequence, and then abeamforming network is used for achieving the composition of a sum and difference beam to meet the needs for satellite communication in motion antenna feeder double frequency and full-simultaneous single-pulse self-tracking.

Description

technical field [0001] The invention relates to a dual-frequency duplex full-simultaneous single-pulse self-tracking satellite communication feed source, which is applied in a satellite communication antenna feed system of a reflective surface in motion, and belongs to the technical field of antennas. Background technique [0002] In the prior art, the antenna feeder system for satellite communication in motion, the feed source adopts Ku / Ka dual-frequency duplex program tracking or Ku / Ka dual-frequency duplex time-division switching single-pulse self-tracking, the type of equipment required And the quantity is large, the overall complexity of the equipment is high, and it is prone to failure; but in effect, only Ku-band monopulse tracking or Ka-band monopulse tracking can be realized, and the self-tracking channel must be switched through the switch network, and it does not have the ability to perform simultaneous tracking. Ku-band and Ka-band simultaneous monopulse tracking...
