In this paper, a setup to obtain an image of the attenuation and the reflectivity of an automotive radome in the 77 GHz band is presented.The characterization of the reflectivity is becoming an important issue to be considered in an automotive radome design because the important effects it can produce in the radar sensor performance such as a false detection of a target or even a blindness of the radar sensor. In addition, the characterization of the attenuation is also important because the reduction in safety due to a possible non-detection of a target.For that reason, a setup to obtain an image of the attenuation and the reflectivity of a radome at the same time is presented. This system can be used to test prototypes in the design process or in the verification of manufactured samples.
