Abstract

The invention discloses a prediction method for an onboard A-E type planar antenna enveloping dimension. The prediction method for the onboard A-E type planar antenna enveloping dimension includes structural characteristic analysis for a planar array antenna and an A-E type antenna seat frame, determining on a motion space and an enveloping boundary, and mathematical description for the enveloping dimension; and establishment of a mathematical prediction model for the enveloping dimension, wherein the model definitely provides a mathematic relation between relevant structural dimensions and the enveloping dimension of the antenna. The prediction method for the onboard A-E type planar antenna enveloping dimension further has the advantages of being accurate in predicted concludes, convenient to apply, easy to compute and the like. The prediction method for the onboard A-E type planar antenna enveloping dimension is especially suitable for the miniaturized onboard A-E type planar array antenna.

Description

technical field [0001] The invention relates to a method for estimating the envelope size of an airborne A-E type flat panel antenna in the field of airborne communication, and is especially suitable for the envelope size of a miniaturized airborne A-E type flat panel array antenna with an antenna diameter between 0.3m and 0.8m. Estimated network size. Background technique [0002] At present, there are more and more applications of airborne A-E flat panel antennas in airborne communication systems, and the demand is also increasing. The envelope size is an indispensable key indicator in the process of project approval, design and evaluation of this type of antenna; the maximum movement space that the antenna can achieve during the continuous full range of azimuth and pitch movement The boundary size is the envelope size of the antenna. There are currently many deficiencies in the estimation of this size: [0003] 1. Not only in the airborne A-E type panel antenna, there ...
