In order to prevent the radar beam from being distorted, the bumper should be kept as flat as
possible, and the thickness should be uniform,any slight bend can have a big impact on the radar
beam.
3.2.4 Bumper shape requirements
The surface of the bumper or shield must be smooth (roughness should be less than one-tenth of a
wavelength, about 400 microns), uniform in thickness, and its radius of curvature should be as large
as possible (small curvature) to reduce distortion and attenuation of the radar beam . Figure 8 shows
the influence of the shape of the bumper on the radar performance, from left to right are bumper
digging (completely unobstructed), parallel, small curvature, thickness gradient, and sharp edge.
