Abstract
This paper describes two computational models for the assessment of effects of nose radomes on the performance of radar antennas. The first model is an improved Physical Optics approach that takes into account the wall thickness and multiple layers of the radome. The second model follows from the accelerated numerical solution of Electric Field and Magnetic Field Integral equations. The models are applied to predict the radiation patterns of a radar antenna behind a generic nose radome and behind a radome of a fighter aircraft. The applicability of the two models is discussed.
