Application of AI-SI Technique to Large Airborne Radome Analysis

摘要

In this paper, the quantitative analysis method of the effects of airborne radome on the sidelobe of antenna enclosed is present ,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 shows more accurate to use the AI-SI method than ray tracing method. This algorithm has higher efficiency and simpler routine than plane wave spectrum method and physical optics method. The calculated simulate results show good agreement with experiment data.
