Abstract

The invention discloses a tri-band measurement and control remote sensing satellite communication multi-functional composite feed source. S-band folding arm oscillator illuminators are installed at the outermost side of a common-caliber corrugated horn through the X / Ku ring loading and the differential mode compatible loading; the S-band folding arm oscillator illuminators are connected with an S-band sum-difference network to form S-band sum-difference signals; common-caliber corrugated horn through the X / Ku ring loading and the differential mode compatible loading is connected with an X / Ku six-port wave separator; Ku-band signals are directly connected backwards for output to connect with a Ku-band orthogonal mode coupler to output orthogonal Ku signals of two paths of vertical polarization and horizontal polarization; X-band signals are subjected to equal-amplitude and in-phase coupling through fourth coupling ports of the X / Ku six-port wave separator to connect with four coupling input ports of an X-band five-end synthesizer, and the output port is connected with the input port of an X-band separator circular polarizer.

Description

technical field [0001] The invention belongs to the technical field of reflector antennas, in particular to a multifunctional composite feed source with S / X / Ku three-band measurement and control, remote sensing, and satellite communication for ground station reflector antennas. Background technique [0002] At present, the existing satellite ground stations use the S-band feed to illuminate the reflector to realize the satellite measurement and control function, use the X-band feed to illuminate the reflector to realize the high bit rate data transmission to the satellite, or use the S / X dual The frequency band feed source illuminates the reflecting surface and realizes the measurement and control data transmission of the satellite at the same time. The satellite reflector antenna uses the Ku-band feed to illuminate the reflector to receive and transmit satellite signals. At present, to realize the functions of measurement and control, remote sensing, and satellite communic...
