Embodiment Construction

[0034] The measurement and installation adjustment process of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] refer to figure 1 , the process of the present invention to large-scale high-precision spherical antenna panel measurement, data processing and adjustment is as follows:

[0036] 1. Initial installation and adjustment of the antenna panel

[0037] Before the antenna panel is installed, a single panel must be strictly measured to meet the panel processing accuracy requirements. In addition, paste a circular target with a cross mark in the center on the target design position of each antenna panel. At the same time, the back frame of the antenna reflector also needs to be measured and adjusted to meet the design requirements. On this basis, each antenna panel can be preliminarily installed one by one to ensure that the panels are basically in place. During the initial installation process, the circumferent...

Abstract

The invention discloses a measurement and installation regulation method for large-scale high-accuracy spherical antenna panel, which comprises: completing nun-contact real-time three-dimension coordinate measurement of antenna panel target ento-ectad from circle to circle with high-accuracy electronic theodolite controlled by computer; building relation between coordinate systems according to measured data to translate target coordinate from measurement coordinate system to antenna coordinate system, translating the data and inputting into software database, and optimizing the tangential and normal regulation values of every panel regulation point; according to calculated result, making space reflection plane coincidence to designed target reflection surface; repeating the said process till satisfying accuracy require. This invention has high regulation accuracy and wide application.

Description

technical field [0001] The invention belongs to the technical field of measurement and adjustment, and relates to the measurement and adjustment of antenna panels. Specifically, it is a large-scale high-precision spherical antenna panel measurement and installation adjustment method, which can be used to guide the rapid measurement and installation adjustment of the large-scale high-precision spherical antenna panel. Background technique [0002] Antennas are mainly used to effectively directional reflect and receive electromagnetic waves, and are part of electronic equipment such as radar and communication. Surface antenna is a main type of antenna, including various parabolic antennas, fan-shaped beam antennas, double reflector antennas, spherical antennas, etc. [0003] In the design of large-scale high-precision antenna systems, the surface accuracy of the antenna reflector is one of the main technical performance indicators of the antenna, which directly affects the el...
