Embodiment Construction

[0079] The present invention will be described in further detail below with reference to the accompanying drawings.

[0080] refer to figure 1 , a rapid thickness design method for aircraft radome based on phase adjustment, the specific steps are as follows:

[0081] Step 1, the thickness of the radome is discretized according to the height direction of the radome.

[0082] Such as figure 2 As shown, along the height of the radome, a coordinate system O-xyz is established with the center of the bottom surface of the radome as the origin and the bottom surface as the xy plane. The height of the radome is along the z direction, and n discrete points are evenly selected along this direction. for z 1 ,z 2 ,…,z n , in the figure θ s Indicates the scan angle of the antenna.

[0083] Step 2, calculating the incident angle at each discrete point during the antenna scanning process.

[0084] (2a) Take m scanning angles within the scanning range of the antenna, denoted as θ si...

Abstract

The invention belongs to the technical field of radar antenna, and provides a rapid thickness design method of an aircraft radome based on phase adjustment. The thickness of the radome is designed bythe incident angle of the radome, and the thickness is corrected by the phase adjustment, so the method improves the design efficiency and also reduces the manufacturing difficulty of the radome on the basis of ensuring the electric performance index, compared with a conventional variable thickness design method.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, in particular to a rapid thickness design method for an aircraft radome based on phase adjustment, which can be used for the structural design of an aircraft radome. [0002] technical background [0003] A radome is a wave-transparent shell that protects the antenna from the natural environment. It is a covering made of natural or artificial dielectric materials, or a specially shaped electromagnetic window composed of a dielectric shell supported by a truss. A well-designed radome, in addition to the functions of protection, conductivity, reliability, concealment and decoration, can also prolong the service life of each part of the entire system, reduce life costs and operating costs, simplify design, and reduce maintenance costs , Ensure the accuracy of the antenna surface and position, and create a good working environment for antenna operators. However, the radome will also affect the...
