Stealth Buildings at Airbus Group Innovations: Low-cost solutions to radio perturbations
Résumé
In this article, we present work being performed at Airbus Group Innovations (AGI), the research center of the Airbus Group, in the area of building stealth. Building restrictions relating to perturbations of aircraft landing systems prevent several tens of square kilometers of land within and close to airports from being used for construction. We present techniques that allow these perturbations to be characterized by numerical simulation and corrected by the placement of specially devised panels, producing a diffraction grating. Examples illustrate a classic thick diffraction grating implanted on a building at Toulouse International Airport in France, and a recently developed thin diffraction grating.
