The invention proposes a small and medium-sized antenna structure system for ship-borne telemetry multi-band beam waveguide, including antenna reflector, antenna seat, transition section and beam waveguide combination; the antenna reflector is a steel radiation beam type modified rotating paraboloid structure, and the reflection panel Independently adjustable high-precision aluminum panels are adopted, the panel accuracy meets the electrical index requirements, the panel structure rigidity meets the mechanical deformation requirements and has redundancy; the antenna base adopts the azimuth and pitch structure, including pitch combination, azimuth combination, and axis angle detection device; The transition section connects the azimuth base and the feed installation cabin inside the hull; the beam waveguide combination includes the feed source and multiple sets of mirror structures, and the beam waveguide feeding method is used to realize X / Ka / S frequency band measurement and control. The invention applies the beam waveguide antenna system to the ship-borne mobile equipment, and under the joint action of the wind load and the ship-sway load, it can ensure that the position and posture of each reflector are correct, and the structural deformation, three-proof and other aspects meet the performance requirements.
Description
technical field [0001] The invention is applied to the fields of ocean telemetry and remote control and technical reconnaissance, and is specifically a small-to-medium-sized antenna structure system of ship-borne telemetry multi-band beam waveguide. Background technique [0002] In order to meet the needs of national defense construction, a set of high-precision, high-frequency and multi-band ocean-going measurement and control system is urgently needed, and the antenna structure system is one of the key equipment of the ship-borne X / Ka / S-band measurement and control system, which plays an important role in the performance of the entire measurement and control system. play a decisive role. [0003] At the current level of technology, the form of feeding the antenna with a beam waveguide has become the first choice. At present, the antennas in the form of beam waveguide feeding at home and abroad are all large-scale antenna systems used in land-based radio astronomy observat...
