Abstract

The invention discloses a transformation method of a UHF-S dual-band parabolic measurement and control antenna. The transformation method of the UHF-S dual-band parabolic measurement and control antenna maintains the S-band receiving capability while increasing an UHF band receiving function. According to the transformation method, a UHF-S dual-band new feed source is directly installed by using an original twelve-meter grignard antenna sub-reflector support to realize UHF band reception, and an original feed system does not need to be modified. The transformation method solves the problem ofreceiving the telemetry information of the deep space exploration microsatellite, and has high engineering application value.

Description

technical field [0001] The invention relates to the field of deep space detection, in particular to a UHF-S dual-band parabolic antenna modification method. Background technique [0002] In order to make full use of the remaining carrying capacity of the rocket during deep space exploration, ultra-long-wave astronomical observation microsatellites are carried in deep space exploration. The micro-satellite carries a VHF / UHF communication module, and plans to carry out technical experiments such as amateur frequency band deep space communication and image transmission, and at the same time provide backup measurement and control functions for the satellite. [0003] The VHF / UHF frequency band is widely used by amateur radio enthusiasts for satellite communication experiments. In this experiment, the UHF downlink link budget is relatively tight, and high antenna gain is required to achieve reception. At present, there is no UHF frequency band in China. Antenna conditions with c...
