Embodiment

[0046] A new type of reflector antenna adjustment and positioning device is used to adjust the accuracy of the small-aperture antenna secondary reflection. The specific method steps are as follows:

[0047] 1) Adjustment and positioning tooling accuracy test

[0048] Before using the adjustment positioning device for calibration, first test its adjustment accuracy, mainly including: X / Y / Z three-way displacement adjustment accuracy; Rx / Ry angle adjustment accuracy. Since the Rz rotation angle is realized by manual adjustment of the auxiliary counter and the adjustment and positioning device, the accuracy test does not include the Rz rotation angle test.

[0049] When adjusting the accuracy test of the positioning device, paste 4 target points evenly on the surface of the fourth upper flange 15 of the device, and adjust the accuracy by testing the target points to detect the displacement and rotation angle of the device. Theodolite system tests the initial coordinate values ​​o...

Abstract

The invention relates to a reflector antenna adjusting and positioning device and method, mainly relates to a small-caliber reflector antenna high-precision, high-efficiency, unstressed adjusting and positioning device and technological method, and belongs to the technical field of antenna assembling and calibrating, wherein the small caliber is the caliber of a reflector antenna and is not larger than 1 m. The adjusting and positioning device performs sub-reflector three-displacement and three-rotating-angle adjusting and positioning, solves the problems that during sub-reflector installation, positioning is not accurate, efficiency is low, the installation stability is poor and installation internal stress is prevented from being generated, and effectively improves the sub-reflector adjusting and positioning precision and efficiency.

Description

technical field [0001] The invention relates to a reflector antenna adjustment and positioning device and method, mainly relating to a small-caliber (small-caliber means that the reflector antenna diameter is not greater than 1m) reflector antenna high-precision, high-efficiency, stress-free adjustment and positioning device and process method, The invention belongs to the technical field of antenna assembly and calibration. Background technique [0002] At present, the adjustment and positioning method of small-caliber (within 1m) antennas has been insufficient for antennas with high requirements for assembly accuracy and electrical performance. Relative to the main reflector of the antenna, the accuracy of the positional relationship is relatively high, and its calibration can only be achieved by adjusting the support rod, which brings about more difficult calibration, longer calibration time, and repeated work. At the same time, since the support rod is suspended in the ...
