Embodiment Construction

[0038] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0039] The invention provides an assembly method of a deployable SAR antenna on a satellite, which realizes the installation of the deployable SAR antenna on a satellite under a two-dimensional unfolding and unloading system; effectively ensures the mutual matching between different interfaces after connection , to ensure the installation accuracy of the SAR antenna on the satellite.

[0040] It mainly includes the following steps:

[0041] Step (1), such as figure 1 Shown is a schematic diagram of the rocker arm deployment and unloading device and the truss. It can be seen from the figure that the rocker arm deployment and unloading device 1 is fixedly installed on the truss 2; figure 2 Shown is a schematic diagram of the rocker arm unfolding and unloading device. It can be seen from the figure that for the rocker arm unfolding and unloading...

Abstract

The invention relates to a method for assembling an unfoldable SAR antenna on a satellite, and relates to the field of on-satellite installation of SAR antennas. The method comprises the following steps: (1) fixedly installing the rocker arm unfolding and unloading device on a truss; Step 2, installing the SAR antenna on the top of the tipping bracket vehicle; 3, realize that butt joint of the SARantenna and the rocker arm deploy and unloading device; 4, remove that SAR antenna from the two-axis turntable; 5, fix and installing that satellite on the top of the overturn bracket vehicle througha two-axis turntable; 6, dock that satellite and the SAR antenna; 7, make a waveguide gasket and fixedly installing that waveguide gasket inside the satellite; 8, remove that SAR antenna from the rocker arm deploy and unloading device, and completing assembly. The invention realizes the satellite mounting of the deployable SAR antenna under the two-dimensional deployment and unloading system. Thematching between different interfaces after connection is effectively ensured, and the mounting accuracy of the SAR antenna on the satellite is ensured.

Description

technical field [0001] The invention relates to the field of satellite installation of a SAR antenna, in particular to an assembly method of a deployable SAR antenna on a satellite. Background technique [0002] A spatial three-dimensional deployable SAR antenna, such as figure 1 and figure 2 As shown, it was developed by a domestic research institution and installed on a satellite platform to realize radar imaging in orbit. The expandable SAR antenna weighs 85Kg, is 1212mm long when folded, 1058mm wide and 2337mm high, and has a complex structure and shape, such as image 3 As shown, the deployable SAR antenna is composed of reflector assembly, feed source assembly, deployment assembly (deployment arm, rotation mechanism, feed source deployment mechanism, compression release device, fourth support structure), reflector installation base plate. [0003] Among them, there are two pressing points between the unfolding assembly and the satellite, wherein, the rotating mecha...
