Embodiment approach

[0058] where gamma 1 =x 1 , gamma 2 =-x 1 +x 2 , γ3=-x 1 +x 4 , gamma 4 =x 1 -x 2 +x 3 -x 4 , gamma 5 =y 1 , gamma 6 =-y 1 +y 2 , gamma 7 =-y 1 +y 4 , gamma 8 =y 1 -y 2 +y 3 -y 4 . Wherein, obtaining the preset number of coordinate points can be any number of coordinate points, and at the same time, for different antenna panel sub-panels, the same coordinate points can be selected in their corresponding unit square domains, or different coordinate points can be selected, but Pick the same amount. In one embodiment, coordinate points can be selected according to the size of the panel. Generally, the interval between two points is about 10-20 cm. For example, for a two-meter-long panel, about 10 points are taken along the length direction. In another implementation manner, 100 coordinate points are selected. Then, a transformation matrix is ​​obtained based on the acquired preset number of coordinate points and a preset transformation matrix expression....

Abstract

The invention discloses an antenna panel adjusting method and device, electronic equipment and a storage medium, and relates to the technical field of antennas. The method comprises the steps of obtaining an overall shape deformation error matrix and an overall panel elastic matrix of a to-be-adjusted antenna panel; based on the overall shape deformation error matrix and the overall panel elasticmatrix, adopting a least square method to obtain a panel displacement adjustment amount; and adjusting the to-be-adjusted antenna panel according to the panel displacement adjustment amount. Accordingto the scheme, the bending deformation condition of the antenna panel is described through the overall panel elastic matrix of the to-be-adjusted antenna panel from the perspective of elastic mechanics, so that the elastic deformation of the panel surface caused by the change of the angular point position of the panel is fully considered; the overall shape deformation error of the antenna panel to be adjusted is described through the overall shape deformation error matrix, the optimal panel displacement adjustment amount is obtained through the least square method, and therefore the adjustment efficiency of the antenna panel is improved.

Description

technical field [0001] The present application relates to the technical field of antennas, and in particular, to an antenna panel adjustment method and device, electronic equipment, and a storage medium. Background technique [0002] The surface of the large-aperture reflector antenna is spliced ​​by hundreds of small panels distributed in concentric rings. The panel is usually a trapezoidal composite panel structure, and the position of the panel can be controlled by adjusting the length of the supporting bolts at the four corners of the panel. The adjustment amount of the corner position of the panel is the key to panel adjustment. [0003] In the prior art, the normal component of the surface shape error corresponding to the corner position of the panel is usually adjusted as the adjustment amount, but using this method requires multiple measurements and adjustments to obtain a surface shape that meets the requirements. This method is actually an iterative adjustment me...
