Velocity Measurement in Automotive Sensing: How FMCW Radar and Lidar Can Work Together

Autonomous vehicles (AVs) depend on an intricate network of camera, radar, lidar, and inertial sensors to navigate safely. Discussing the merits and drawbacks of individual sensors is one of the more consistent "water-cooler topics" in the autonomous driving industry. Although this sensor face-off is entertaining, it is sometimes more useful to consider how two sensors can work together. I will discuss two sensors that can directly sense velocity in the context of future AV capability.
