Within the scope of this application note, the fundamental principle of frequency-modulated continuous wave car radar and typical car radar deployment and positioning possibilities have been discussed. It has shown that the insertion loss or phase change of the material in front of a car radar can have some significant influence upon the radar’s detection range. It is possible to visualize the impact of materials in front of the radar by conducting VNA-based transmission and phase measurements. As a result, it is possible to judge if such material might have an influence upon the radar detection range. In the car emblem used in the examples, the measurement results show a nearly ideal behaviour proving that the car radar’s detection range is most likely not negatively impacted by a two-way insertion loss.
