Abstract

The invention provides a trapezoidal satellite structure suitable for a radar antenna and a manufacturing method. The trapezoidal satellite structure comprises a cabin, a first side plate 15 and a second side plate 16; the cabin comprises an upper cabin 1, a middle cabin 2 and a lower cabin 3, which are sequentially connected and form a trapezoidal structure; the first slide plate 15 is clung to the sides of the upper cabin 1, the middle cabin 2 and the lower cabin 3; the second side plate 16 is clung to the sides of the upper cabin 1, the middle cabin 2 and the lower cabin 3; and a plane where the central plane of the first side plate 15 is positioned intersects with that where the central plane of the second side plate 16. The trapezoidal satellite structure and the manufacturing methodcan ensure the reliable mounting of a synthetic aperture radar antenna, and can reduce the centroid of a whole satellite and the response of the synthetic aperture radar antenna; and the fundamental frequency of the whole satellite meets the requirement of a carrier rocket, and the dimensional stability to heating of the whole satellite meets the detection precision index requirement of the synthetic aperture radar antenna.

Description

technical field [0001] The invention relates to the field of satellite structures, in particular to a trapezoidal satellite structure suitable for radar antennas and a manufacturing method, in particular to a trapezoidal satellite structure of a large-size synthetic aperture radar antenna that can be folded and folded. Background technique [0002] When the large-scale synthetic aperture radar antenna works in orbit, it is usually in a rectangular configuration. Due to the limitation of the internal space of the launch vehicle fairing, the synthetic aperture radar antenna needs to be folded and divided into two wings, which are respectively compressed and installed on both sides of the satellite structure through explosive bolts. . After the folded configuration of the synthetic aperture radar antenna is formed, the number and position of the pressing points distributed on it are determined. After it is installed on the satellite structure, the center of mass, fundamental fr...
