One of the strengths of radar technology is its unique ability to detect objects in 3D space. This makes it ideal to use as part of a robotic navigation system. Radar can detect many objects simultaneously, and report the distance, angle, and velocity of each, something lidar and cameras struggle to do. Radar's strength match the weaknesses of lidar and cameras making them a perfect combination sensor.
Radar can track moving objects really well, for example, tracking people or vehicles. The RadarIQ module has 110° vision and is designed with plug-and-play integration for ROS, PC, Raspberry Pi and Arduino.
