UWB-Radar Cross Section Measurements in the Fresnel Region and Real Environment

Abstract : This paper presents a novel method to approximate the specular radar cross section of a flat plate (with known dimensions) in the Fresnel region. The proposed method relies on averaging the contribution from discrete current elements at the horn antenna aperture and discrete current elements on the target. The approximations made to estimate the phase difference result in the classical flat plate radar cross section when the antennas-target distance approaches the far field. A computing time saving technique with Fresnel integrals is proposed in order to calculate the phase difference. The experimental validation of the proposed technique demonstrates reasonable agreement with the theoretical far field radar cross section. © 2019 Antenna Branch of Chinese Institute of Electronics.
