Unlike optical cameras that fail in poor lighting, mmWave radar usesradio waves to penetrate obstacles and generate detailed 3D maps of fields. In agricultural spraying drones, this technology enables precise navigation and targeted spraying, ensuring chemicals are applied only where needed.
There are two types of mmwave radar sensing in agricultural spraying drones. The altimeter radar makes sustainable flying height to realize the effective spraying.
The collision avoidance radar brings safety to the drones in terms of working in fields, which could have trees, poles and different obstacles.
