Comparison of matching layers for automotive radome design

[摘要] Hidden integration of 79 GHz sensors behind plastic and painted fasciarepresents a challenging task since both electromagnetic and car body designconstraints have to be met. This paper compares different possibilities forlow-cost integration of radar sensors. Based on a model for stratified media,a study of the most important parameters such as bandwidth, angle andtolerances is shown. Our results suggest that for plastic fascia, therequirements of future radar sensors can be met with low-cost matching. Evenwith metallic paints, the requirements imposed by modern 79 GHz radar sensorscan be met under certain conditions.
