The ground like radar module uses millimeter-wave radar technology. Through continuous scanning of the radar, the aircraft can sense the terrain change in the flight direction, and adjust the flying height in time according to the terrain and crop height to achieve ground-like flight and ensure uniform spraying in flight . The ground-like radar module has stable detection performance and good environmental applicability, strong anti-interference ability, not affected by light, long detection distance, and has the characteristics of all weather and all day.

Obstacle avoidance radar module is mainly used to measure the relative distance between the drone and the obstacle in front of the flight, so as to avoid the obstacle effectively. Obstacle avoidance radar adopts 24GHz radar technology, which can work in all weather under strong light, high temperature, fog, dust, wind and night. Its sensitivity is high, the detection distance is long, the signal transmission is fast and stable. Electric wires, small trees with a trunk of 10 cm, people with a height of 1.7 m, and telephone poles with a height of 15 cm play an excellent obstacle avoidance function for high-speed drones, which is very suitable for plant protection drones to work in complex outdoor environments.
