Partners of the VIVID consortium under the lead of the University of Applied Sciences in Kempten, Germany, conducted jointly with the Kanagawa Institute of Technology from the DIVP consortium a sensor test campaign at the National Research Institute for Earth Science and Disaster Resilience (NIED) in Tsukuba, Japan, in Fall 2022. This measurement campaign aimed at obtaining sensor data as an input for rain modeling, including signal attenuation, signal-to-noise ratio (SNR), and backscattering, for LiDAR and RADAR sensors of different types.
For these tests, we used standardized corner reflectors, Lambertian reflectors, and a real passenger car Toyota Alphard. LiDAR and RADAR signals were measured for rain rates varying from light rain (16 mm/h) to very heavy rain (98 mm/h). Evaluating the measurement data will help validate rain models for LiDAR and RADAR sensors.
Detailed results will be made accessible to the interested public soon. Stay tuned.
