Analysis of Tangent Oval Radome Based On Matla

摘要

Radome always brings influence on antenna wave packet. The influence mainly includes amplitude attenuation, distortion of main wave packet form and boost of adaxial minor lobe level. Ablation dielectric is generated during high speed flight of aerocraft; it brings different influence to antenna wave packet. This paper analyses the influence of radome and ablation dielectric on antenna pattern with Plane Wave Spectrum-Surface Integration method (PWS-SI), and simulated in Matlab.
