Abstract

The invention provides a deformation conformal array antenna modeling method based on a high-order moment method, and aims to solve the technical problem that a deformation conformal array antenna calculation model built in the prior art is poor in accuracy. The method comprises the following implementation steps: obtaining a deformation curve function Z(x) of a to-be-constructed deformation conformal array antenna calculation model; establishing an undeformed conformal array antenna calculation model based on a high-order moment method; obtaining coordinates of projection points of N vertexeson Z(x) in the undeformed conformal array antenna calculation model; and constructing a deformation conformal array antenna calculation model. Projection points of all vertexes in an undeformed conformal array antenna calculation model on Z(x) are connected, a deformation conformal array antenna calculation model which is tightly connected among the grids is constructed; and the side length of each grid in the high-order moment method adaptive quadrilateral subdivision grid is small, and the linear distance of each connected projection point can be equal to the curve length of the projectionpoints on Z (x), so that the transition of the calculation model is smooth, and the accuracy of the calculation model is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic simulation, and relates to a deformation conformal array antenna modeling method, in particular to a deformation conformal array antenna modeling method based on the high-order moment method, which can be used to calculate the deformation conformal array antenna model Simulation analysis of electromagnetic characteristics. Background technique [0002] The conformal array antenna is attached to the surface of the carrier and fits with the carrier, and can conform to the surface of the flexible large-span carrier platform running at high speed. The flexible large-span is affected by the harsh external environment and its own load during operation. Deformation is easy to occur, resulting in deformation of the conformal array antenna, causing changes in the position of the antenna unit, and deterioration of electrical performance parameters, such as pattern beam pointing offset, gain reductio...
