UAV Radar Altimeters
Benefits of Radar Altimeters for Drones
Radar technology, while similar to LiDAR, offers several meaningful advantages for altitude measurement in environments frequently encountered by drones and robotic vehicles.
- Radar operates effectively in heavy rain, snow, and fog without compromising performance.
- Radar is especially effective in environments with large water bodies,where LiDAR signals may be absorbed.
- Radar excels in dense vegetation, outperforming standard LiDAR in areas with bushes and tree canopies.
Additionally, radar surpasses vision-based technologies in several critical aspects.
