  • Road Spray in Radar and Lidar Data

    Virtual testing always entails the modeling of automotive perception sensors and their environment. In the real world, these sensors are not only exposed to global weather conditions, like rain, fog, snow etc., but environmental influences also appear locally. Road spray is one of the more challenging occurrences, because it involves other moving objects in the scenario. This data set is designed to systematically analyze the influence of road spray on lidar and radar sensors. It consists of sensor measurements of two vehicle classes driving over asphalt with three water levels to differentiate multiple influence factors.

    There are two different kinds of logical scenarios:

    1. The ego vehicle is positioned stationary next to the watered lane. The object vehicles are driving past the ego with different velocities and different water film heights.
    2. The ego vehicle is following the object vehicles in different distances with different velocities.
      The data set will be publicly available shortly under

  • Perception Sensors in Adverse Weather

    In the real world, perception sensors are exposed to adverse influences by environmental conditions like rain, fog, snow etc. Therefore, such influences need to be reflected in simulation models, but prior to modeling, they need to be systematically assessed in the real world. This measurement campaign consists of a static test setup over the course of 6 months in fall, winter and spring containing weather conditions like rain, snow, fog and direct sun light in different intensities. The test was setup on a free area on the August-Euler-Airfield in Darmstadt, Germany. The first element of the test setup is a measuring station, where automotive perception sensors and weather sensors as reference are connected to a measurement PC and measurements are triggered automatically. The second element of the setup consists of multiple reference targets for radar and lidar at distances of 50 to 70 m. These targets provide defined reflectivities to compare the influence of different environmental conditions on the sensor’s intensity readings. The corresponding data set will be publicly available shortly under

  • RCS profiles of different road users in real world measurements

    A key part of virtual testing of automated driving functions is the implementation and validation of perception sensor models. With this measurement campaign, radar cross-sections (RCS) of multiple objects with different aspect angles are examined. The experiment is set up as a slalom course to measure the RCS under realistic conditions in a real world environment on the August-Euler-Airfield in Darmstadt, Germany. The slalom was set up in a reproducible manner by placing markers and pylons on the test track. The ego vehicle and the objects drove through the slalom at a constant speed. Each test drive contains 10 slalom periods and for each object 10 test drives were conducted. The dataset will be available in the near future under
