METHOD AND DEVICE FOR EVALUATING ELECTRICAL PERFORMANCE OF RADOME

摘要

Method and device for evaluating the electrical performance of an antenna cover. The method for evaluating the electrical performance of the antenna cover comprises: acquiring electromagnetic parameter information of an antenna and parameter information of an antenna cover; calculating far-field information of the antenna and far-field information of an antenna system on the basis of the electromagnetic parameter information of the antenna and of the parameter information of the antenna cover; and calculating electrical performance parameter information of the antenna cover on the basis of the far-field information of the antenna and of the far-field information of the antenna system. By means of the actual measurement of the electromagnetic parameter information of the antenna and of the parameter information of the antenna cover, the calculation of the far-field information of the antenna and of the far-field information of the antenna system, and the electrical performance parameter information of the antenna cover thus produced, without relying on a precise digital model of the antenna or when the antenna system is of increased complexity, calculation precision is ensured, the operability of the evaluation of the electrical performance of the antenna cover is greatly increased, and calculation precision is effectively increased.
