XAG FRD2488 Sensor System

Introduction

The sensing module is applied to the perception of agricultural operation environment, detecting the distance, speed and orientation of people, trees, wires, poles and other targets in the environment, and output 3D position point cloud information and speed information. The back-end processor uses the point cloud output by the radar for target detection and identification, and establishes a real-time map to provide agricultural UAVs with route planning and obstacle avoidance. The millimeter-wave radar has a head motor inside, which can realize the function of rocking scanning or maintaining a fixed Angle. The visual function produces images.
