Problems solved by technology

[0003] The ground reflector with solid surface panel has the following defects: in order to ensure the surface accuracy of the ground reflector, it is necessary to increase the rigidity of the reflector panel and the supporting back frame, but the increase in stiffness increases the mass, and the increase in mass increases the gravity Deformation, in order to reduce the gravity deformation, it is necessary to further increase the stiffness of the antenna base
But this cable net structure cannot be directly used on the ground

Abstract

The invention discloses a ground reflector in a cable network structure. The ground reflector comprises a plurality of rectangular truss frame units (1), a plurality of ring structure connecting joints (2), a position and pitching control device (3), a feed source (4), an upper ring (5), a lower ring (6), a center cylinder (7), network surface cables (8), fastening cables (9) and dragging cables (11), wherein supporting cables (10) are mounted between the network surface cables and the fastening cables; the deformation of the network surface cables can be controlled by regulating the lengths of the supporting cables, and the shape of a reflecting surface is changed; through regulating and controlling the lengths of three telescopic rod units in the position and pitching control device, a position angle and a pitching angle of the ground reflector in the cable network structure satisfy the required positions and the required postures. The ground reflector is simple in structure and light and flexible, the position and the pitching of the ground reflector can be accurately controlled, the structural rigidity is improved, the surface accuracy of the reflector can be ensured, and the ground reflector is used for communication, navigation, detection, tracking, measurement and control for the ground surface environment.

Description

technical field [0001] The invention belongs to the technical field of communication and electronics, in particular to a cable net structure reflector, which can be used for converging or reflecting electromagnetic energy or light energy on the ground or on ships. Background technique [0002] With the continuous development of aerospace, communication and other technologies, applications such as communication, navigation, detection, tracking, measurement and control are inseparable from ground fully movable large reflectors, and the caliber is getting larger and larger. The ground fully movable large-scale reflector structure includes a reflective surface, a supporting back frame, and an adjustment device for pitch angle and azimuth angle. Among them, the surface accuracy of the reflector is an important index to ensure the working accuracy of the ground reflector. Due to the effects of gravity, wind load, and rain and snow load in the surface environment, in order to ensu...
