Polarimetric scattering mechanism analysis of automotive landmarks

This paper presents a detailed investigation of the scattering mechanisms occurring at different traffic signs and a guide post in the 77 GHz automotive radar frequency band. By utilizing a polarimetric ISAR imaging process, the scattering centers are spatially resolved in a 2D image plane. The proposed phase drift compensation approach provides the basis for a valid analysis of scatterers. A potential vehicle self-localization relying on such landmarks will benefit from this knowledge.
