Abstract

The present invention discloses a patch integration formula-based umbrella antenna structure optimization design method. The method comprises the following specific steps: inputting the structure parameters and the electrical parameters of an umbrella antenna; calculating the optimal focal length of the umbrella antenna; calculating the segment number of antenna ribs; calculating the coordinates of points on the ribs; calculating the coordinates of points between adjacent ribs; generating all the node coordinates of the umbrella antenna; calculating the coefficient of a patch plane equation; calculating the coefficient of a triangle edge equation; calculating the projection area of the triangle; calculating the axial error of triangle patches; outputting the axial precision of the umbrella antenna; judging whether the axial precision of the umbrella antenna meets the requirement or not; outputting the structure parameters of the umbrella antenna; and updating the structure parameters of the umbrella antenna. According to the technical scheme of the invention, the characteristics of the umbrella antenna spliced by patches are considered. Based on the patch integration formula, the axial precision of the umbrella antenna is analyzed. Therefore, by adopting the method, the mechanical structure design and the electromechanical integrated optimization design of the umbrella antenna are guided.

Description

technical field

[0001] The invention belongs to the technical field of radar antennas, in particular to an umbrella-shaped antenna structure optimization design method based on a patch integral formula in the field of radar antennas. Background technique

[0002] As a kind of space-borne deployable antenna, the umbrella antenna is a kind of space-borne deployable antenna that has been studied and put into use earlier. Umbrella antennas designed using the characteristics of flexible wire mesh and rigid ribs are being gradually applied to the design of high-gain, light-weight spaceborne antennas. Umbrella antennas use flexible wire mesh to form the antenna reflection surface, which inevitably introduces patch stitching errors, which are principle errors that need to be considered in the concept stage of umbrella antennas. At the same time, the umbrella antenna is affected by external loads such as thermal shock and attitude change in orbit, and the shape of its reflective sur...
