Radar Altimeters for UAVs

The advantages of drone radar altimeters

While radar and LiDAR have some similarities, radar technology provides a number of crucial advantages for altitude sensing in environments commonly experienced by drones and robotic vehicles.
UAV Altitude Radar

  • Radar can function in heavy rain, snow, and fog without experiencing any loss in performance
  • Radar is highly suited for applications where large bodies of water are present, whereas LiDAR signals are absorbed
  • Radar offers superior performance in the presence of bushes, tree canopies and heavy vegetation, compared to standard LiDAR

Radar also outperforms vision-based technologies in several key areas.
