Abstract :
In this paper, the quantitative analysis of the effects of airborne radome on the sidelobe of the 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 the ray tracing method. This algorithm has higher efficiency and simpler routine than the plane wave spectrum method and physical optics method. The calculated simulation results show good agreement with experimental data
