This webinar shows how Altair WinProp considers the full environment including buildings, cars, street objects in order to get accurate representations of the radio waves impinging on the installed car antennas and the multipath radar channels including reflections, diffractions and scattered contributions. For the efficient analysis the car objects can be also replaced by their corresponding radar cross sections (pre-calculated in Altair Feko). Thus allowing the realistic and fully reproducible evaluations of different options for the antennas and sensors including their integration and configuration.
