Abstract

The invention discloses an electrical property evaluation method and device for a radome. The electrical property evaluation method for the radome comprises the following steps that: according to measurement, obtaining antenna radiation near region electric field information, and calculating the caliber surface electric field information of the antenna according to the near region electric field information; obtaining the model data information of the radome, and obtaining the subdivision surface meta-information of the radome according to the model data information of the radome; according tothe caliber surface electric field information of the antenna and the subdivision surface meta-information of the radome, calculating the far field information of the antenna and the far field information of an antenna system; and according to the far field information of the antenna and the far field information of an antenna system, calculating the electrical property parameter information of the radome. The radiation near region electric field information of the antenna is practically measured to obtain the caliber surface electric field information of the antenna so as to obtain the performance parameter information of the radome, calculation accuracy is guaranteed under a situation that antenna digital-to-analogue input is not depended, and the maneuverability of the electrical property evaluation of the antenna system of ''antenna+radome'' can be greatly improved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a method and device for evaluating electrical performance of a radome. Background technique [0002] In the prior art, the physical optics algorithm is usually used to calculate the near field incident on the inner wall of the radome according to the Fourier transform relationship between the antenna aperture surface electric field distribution or the antenna plane wave spectrum and the antenna aperture surface electric field distribution, and then , modeled on the ray principle of geometric optics, to compute the transmitted and reflected fields on a local plane. [0003] However, this electrical performance evaluation method has very obvious defects. For example, the electric field information of the antenna aperture surface is usually obtained based on the full-wave simulation of the antenna digital model. In the case of no antenna digital model, approximate modeling is usually used fo...
