Laser radar sensors offer high angular resolution and accurate range, making them suitable for advanced driver assistance, but their performance is affected by weather conditions. This study reviews the physical principles causing laser radar signal disturbances and investigates their impact. The authors analyze the physical principles behind laser radar signal disturbances and model their effects. The transmission models were used to generate signals in a new laser radar target simulator, providing the first worldwide hardware‑in‑the‑loop test capability for automotive lidar systems. Abstract.
Abstract. Laser radar (lidar) sensors provide outstanding angular resolution along with highly accurate range measurements and thus they were proposed as a part of a high performance perception system for advanced driver assistant functions. Based on optical signal transmission and reception, laser radar systems are influenced by weather phenomena. This work provides an overview on the different physical principles responsible for laser radar signal disturbance and theoretical investigations for estimation of their influence. Finally, the transmission models are applied for signal generation in a newly developed laser radar target simulator providing – to our knowledge – worldwide first HIL test capability for automotive laser radar systems.
