What is the primary functional use of a RADAR or LiDAR sensor?

The primary functional use of RADAR (Radio Detection and Ranging) or LiDAR (Light Detection and Ranging) sensors is measuring distances. These technologies work by sending out a signal (radio waves for RADAR and laser light for LiDAR) and then measuring the time it takes for the signal to return after reflecting off an object. This allows for precise distance calculations to determine the position or shape of the object being measured.

While RADAR and LiDAR can also support diverse applications, such as mapping geographical terrain and potentially participating in detecting chemical compositions when integrated into specific systems, their fundamental operation revolves around distance measurement. This capability is essential not only for navigation and obstacle avoidance in unmanned air systems but also for various applications in surveying, forestry, and environmental monitoring.
