Analysis of influence of plastic bumper on radio wave characteristics
From the standpoint of vehicle appearance, vehicle radar units should be located behind plastic bumpers. Plastic bumpers are made of dielectric material, which causes reflection, scattering, refraction, and diffraction of radio wave. These influences must be taken into consideration to ensure sufficient radar performance. In this paper, PAM-CEM (FDTD) is used to analyze the influence of dielectric material on radar radio wave.
