一种多频段共口径测控数传一体化天线系统设计与实现
Design and Implementation of a Multiband Common Aperture TT&C and Data Receiving Integrated Antenna System
摘要
Abstract
For the requirements of high-quality reception and overhead tracking in the C/X/Ka-band satellite signals by civil aeronau-tics telemetry tracking and command(TT&C)and data receiving integrated ground satellite station,a multiband common aperture TT&C and data receiving integrated antenna system is developed which solves the technical problems of high efficiency transmit-receive shared,tracking in the whole airspace for the C/X/Ka-band low earth orbit satellite signals,and large tracking errors during zenith pass in antenna systems.High-precision antenna frequency continuous handover technology based on mechanical self-locking device and servo control technology based on multi-information fusion are proposed in this paper.A triaxial 7.3 m C/X/Ka-band reflector antenna prototype based on the electric frequency continuous handover system is developed,and relevant testing and verifi-cation are completed,achieving stable zenith passing tracking for C/X/Ka-band low earth orbit satellite signals.The on-site test results show that the designed antenna prototype meets design requirements for the receiving gain,the first sidelobe,null depth of different beams,pointing accuracy,and tracking accuracy.Notably,the root mean square tracking error for the X-band reaches 0.032 0°,while the Ka-band root mean square tracking error reaches 0.012 8°,both are no more than one-tenth of the half-power beam width.The proposed scheme provides important guidance for the design of multi-band TT&C antenna system.关键词
