Indoor Measurement Research on Polarimetric Scattering Characteristics of UAV

Abstract

Knowledge of target polarization characteristics is valuable for radar target detection, classification, and identification. We conducted experimental research on an Unmanned Aerial Vehicle (UAV) with complex materials and structures to determine the differences in polarimetric scattering between the UAV and its perfect electric conductor model. To illustrate the coherence of the entire UAV and its components using polarimetric scattering, we measured and analyzed each part. The results reveal that the airframe and aerofoils directly influence the depolarization, and that the polarimetric scattering characteristics of the airframe represent the primary source for the whole UAV.
