Embodiment Construction

[0054] Such as figure 1 As shown, a mesh antenna shaped beam design method based on electromechanical integration is an electromechanical integrated shaped beam design method that achieves the shape electrical performance requirements as much as possible by directly designing the force density of the mesh antenna structure. Including the following steps:

[0055] Step 101: Determine the basic electrical parameters and geometric parameters of the mesh antenna, including: the operating frequency f of the antenna, the aperture D of the antenna, the focal length F of the front cable net, the offset distance p of the front cable net, and the height H of the antenna;

[0056] Step 102: According to the cutting method of the offset paraboloid, the initial shape of the front cable net and the rear cable net is obtained; the generation method of the antenna paraboloid is as follows figure 2 As shown, where OXYZ is the global coordinate system of the antenna, and oxyz is the local coo...

Abstract

The invention discloses an electromechanical-integration-based shaped beam design method for a satellite-borne mesh antenna. In the method, firstly, an electromechanical-integration-based shaped design optimization model for the mesh antenna is built, the force density of a cable net serves as the design variable of the optimization model directly, and under the condition that the cable net is in a tensioned and balanced state without loose cables, the method aims to achieve the targets of enabling the electrical performance of a far field to meet the shaping requirement as far as possible and making the tension of the cable net uniform as far as possible; then, iterative solving is performed on the optimization model till the optimal comprehensive target of the electrical performance and the tension uniformity is achieved, and shaped beam design of the mesh antenna is completed.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, in particular to a method for designing a shaped beam of a space-borne mesh antenna based on electromechanical integration, which is applied to the design of a shaped beam of a space-borne mesh antenna. Background technique [0002] The shaped reflector antenna has the characteristics of high efficiency and low signal interference in the adjacent area of ​​the service area, and is widely used in satellite communications; at the same time, the surrounding truss-type deployable mesh antenna has the characteristics of light weight, small volume and short period , has become a form of space deployable antenna that has attracted much attention from the aerospace community in recent years; therefore, it is necessary to conduct in-depth research on the shapeability and corresponding shape forming methods of the surrounding truss-type deployable mesh antenna. The peripheral truss-type deployable m...
