20m UAV obstacle avoidance millimeter wave radar

Key Features of R21-1 UAV Obstacle Avoidance Millimeter-Wave Radar

1. Stable Target Tracking: The radar can track detected targets at a range of over 20 meters, enabling autonomous obstacle avoidance for unmanned aerial vehicles (UAVs).

2. High Detection Accuracy: Compared to 24GHz radars, the R21-1 offers a 3x improvement in ranging resolution, resulting in enhanced obstacle identification capabilities.

3. Narrow Radar Beam: The focused beam design concentrates energy in the center, minimizing ground clutter interference when the UAV operates at tilted attitudes, effectively eliminating the “low-altitude skimming” issue.

4. Robust Interference Resistance: The radar is unaffected by light, weather, environmental noise, and electromagnetic interference from the UAV, ensuring reliable performance in diverse conditions.

5. Compact Size: The R21-1’s compact 79GHz millimeter-wave design enhances its versatility and adaptability to a wide range of applications. Customers can adjust the radar’s sensitivity based on their specific operational environments.
