Radar Cross-Section Measurements of a Full-Scale Aircraft Duct/Engine Structure

Abstract

Cavity radar cross-section (RCS) data are measured from a full-sized generic aircraft duct/engine mock-up experimental apparatus. Details of the experimental measurements and characterization of the RCS from a generic aircraft engine inlet with a fan assembly embedded inside are described. The experimental results reveal that the azimuthal RCS patterns from an aircraft engine inlet with fan components embedded inside are very complex
