Title:
ASSEMBLY METHOD AND SYSTEM FOR FLAT ARRAY SAR ANTENNA UNFOLDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/089581
Kind Code:
A1
Abstract:
An assembly method and system for a flat array SAR antenna unfolding system. The positions of an antenna panel (2) and a coaxial hinge (10) are measured by a measuring system; a control system (11) controls a panel attitude adjusting mechanism (3) and a panel supporting mechanism (4) to adjust the position and flatness of the antenna panel (2) according to a measurement result; and a hinge attitude adjusting mechanism (8) is controlled to adjust the spatial position of the coaxial hinge (10). The present invention realizes the high-precision, automatic and quick assembly and adjustment of the panel and the hinge of the flat array SAR antenna unfolding system, can meet the assembly requirements that the flatness of the panel is ≤0.1 mm, the displacement adjustment precision is ≤0.02 mm, and the angle adjustment precision is ≤0.01° within the range of 10 m × 2.5 m, and improves the assembly precision and efficiency of large-scale flat array SAR antenna unfolding systems.
