What distinguishing feature does LIDAR have compared to RADAR?

LIDAR, which stands for Light Detection and Ranging, utilizes light pulses, typically in the form of laser beams, to measure distances to a target. This mechanism allows for high-resolution mapping and precise measurements of various surfaces. The light pulses emitted from LIDAR systems are reflected off objects and then measured for distance based on the time it takes for the light to return.

In contrast, RADAR systems use radio waves instead of light pulses to detect objects and their locations. This difference in the type of electromagnetic radiation utilized is what primarily differentiates LIDAR from RADAR. While sound waves are the foundation of sonar technology, they are not employed by LIDAR, nor do they operate specifically through solid objects as some other types of sensing technologies might, but rather reflect off surfaces. Therefore, the distinguishing feature of LIDAR being its use of light pulses is accurate and reflects a key aspect of how the technology functions compared to RADAR.
