The rapid development of UAV technology has made UAV widely used in all walks of life. However, the flight safety of UAV has been a major bottleneck restricting its development. In recent years, radar technology has been rapidly developed in the field of UAV, and has made important contributions to the improvement of UAV flight safety.
- UAV radar altimeter: mainly used to assist takeoff and landing, to measure the relative altitude to the ground in real time to improve the reliability of UAV.
- UAV obstacle avoidance radar: mainly detects targets 50 meters ahead, realizes autonomous flight, and improves flight safety.
- Imitation mine-radar: mainly detects the terrain changes ahead in real time, and adjusts the flight altitude according to the terrain height to improve flight safety and stability.
Drone radar altimeterUav radar altimeter is the most widely used radar type in UAVs. It calculates the relative altitude of the drone to the ground by transmitting radio waves and receiving signals reflected back from the ground. The measuring accuracy of UAV radar altimeter can reach ±2cm, which can effectively prevent the ground collision of UAV during takeoff and landing.
The application of UAV radar altimeter can improve the reliability of UAV take-off and landing. The UAV radar altimeter can provide the altitude information of the UAV, help the UAV to maintain a stable flight state during takeoff and landing, and avoid ground collision.
Uav obstacle avoidance radar is a new technology developed in recent years. It detects targets in the surrounding environment by transmitting radio waves and receiving signals reflected back from the target. Uav obstacle avoidance radar can detect objects that are difficult for UAV vision systems to detect, such as low-flying birds, floating balloons, and so on.
The application of UAV obstacle avoidance radar can improve the flight safety of UAV. Uav obstacle avoidance radar can provide the situation information of the surrounding environment, help the UAV autonomously avoid obstacles and avoid collisions.
Mine-like radar is a new technology that has been applied in UAV field in recent years. It builds a terrain model by emitting radio waves and receiving signals that bounce back from the ground. Mine-like radar can help drones fly in complex terrain environments and avoid ground collisions or falls.
The application of imitation radar can improve the flight stability of UAV. The mine-like radar can provide the UAV with terrain information, help the UAV maintain a stable flying attitude, and avoid the loss of control in the complex terrain environment.
The application of these three radar technologies provides multiple guarantees for the flight safety of UAVs. The UAV radar altimeter improves the reliability of takeoff and landing. The UAV obstacle avoidance radar improves the flight safety of UAV. The imitation radar improves the flight stability of UAV.
