Physically based radar simulation parameter of road surfaces in OpenMATERIAL

To enable autonomous driving simulations are getting more and more important. A common method is ray tracing depending on geometrical optics. However, this method is not always sufficient, but has to be enhanced. It can be essential to consider material parameter, which have to be provided anyhow. OpenMATERIAL is a project collecting reliable physically based material parameter data for automotive simulations, which is published open source. Ideally the database will contain data of all important materials in future. Furthermore, the datasets have to distinguish for all in automotive applications implemented sensor types. To pursue this idea we here suggest material parameters that are important for radar applications and integrate them in OpenMATERIAL. Moreover, we provide material parameter files containing information regarding radar wave behaviour for five different road surface types in this format.
