Compare LiDAR and Radar sensors for ADAS applications.

LiDAR creates detailed 3D point clouds with high angular resolution for precise object detection and classification, but is expensive and affected by weather conditions. Radar excels in velocity measurement, works in all weather, is cost-effective, but has lower resolution. Modern ADAS uses sensor fusion: radar for long-range detection and velocity, camera for classification, and optionally LiDAR for precise spatial mapping. Companies like Ola Electric and Tata are integrating multiple sensor modalities.
