Abstract

In this paper

the quantitative analysis method of the effects of airborne radome on the sidelobe of antenna enclosed is presented

by means of vector aperture-integration and surface-integration(AI-SI).When the radome dimension in elevation is around λ and the wall curvature varies significantly

it is more accurate to use the AI-SI method than 3 dimension ray tracking method.The calculated simulation results show good agreement with the scaled experimental data and the validity of the algorithm has been proven.
