Integration of Antennas Onboard Vehicles and Diffraction by Large and Complex Structures With Multiple-Domain–Multiple-Methods Techniques

In this paper, we present a review of recent developments achieved in a multiple-domain-multiple-method calculation methodology in the frequency domain for the prediction of airborne antenna radiation and the diffraction of large targets. Furthermore, special attention is paid both to proposing a consistent and collaborative calculation procedure that ensures that industrial confidentiality is protected and also to guaranteeing large gains in accuracy and computing time in the parametric study phase on large objects (search for an optimal installation of the radiating parts, optimization of the antenna design mounted on the vehicle, radar cross-section modulation induced by fan rotations, etc.).
