Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0037] The radiation characteristic testing device of a whole satellite antenna with a frame structure provided by the present invention realizes three-dimensional rotation of a measured object on an ordinary two-dimensional antenna test turntable through built-in components. The simulated star and built-in components adopt a modular design, which is characterized in that all components are disassembled into several parts, transported after disassembly, and reassembled at the test site.

Abstract

The invention provides a whole-spacecraft antenna radiation characteristic test device in a frame structure. Through built-in components, rotation of a tested model star in a rolling direction is realized, and in match with a two-dimensional test turntable, three-dimensional rotation of a simulated star is finally realized. The built-in components comprise a satellite connection frame, a rotation shaft, a main force bearing support and a lateral force bearing support, wherein the satellite connection frame provides a connection interface for the simulated star and the rotation shaft, thereby realizing interconnection between the rotation shaft and the simulated star; the rotation shaft provides 360-DEG axial rotation towards the ground for the simulated star; the lateral force bearing support is used for fixing the rotation shaft and provides a connection interface for the rotation shaft and the main force bearing support, thereby realizing interconnection between the rotation shaft and the main force bearing support; and the main force bearing support provides a connection interface for a rotation shaft support and a ground test turntable, thereby realizing interconnection between the simulated star and the test turntable. Antenna radiation characteristic test under any satellite attitude on the two-dimensional turntable can be realized.

Description

technical field [0001] The invention relates to the design of a radiation characteristic test device for a whole-satellite antenna, more specifically, a design of a test device for antenna radiation characteristics that meets the requirements of realizing the antenna radiation characteristics in any attitude of the whole star on a two-dimensional test turntable. Background technique [0002] With the development of satellite technology and the continuous expansion of application scope, the number and types of payloads on the satellite are increasing, and the layout of the entire satellite is becoming more and more crowded, which seriously affects the performance of the antenna on the satellite. [0003] Satellite designers will comprehensively consider various payloads on the satellite, including the field of view requirements of antennas, when making satellite layouts. This is mainly considered from the perspective of no occlusion in the optical field of view, which is appl...
