What does "target tracking" mean in the context of Lidar?

In the context of Lidar, "target tracking" refers to the ability to follow a specific vehicle to measure its speed over time. This involves not only capturing the initial data but also maintaining a continuous measurement of that vehicle's location and speed. The Lidar system utilizes its rapid pulse emissions and reflective data to calculate how far the vehicle is at any given moment and how quickly it is moving relative to the Lidar unit.

This capability is essential for various applications, including traffic monitoring and law enforcement, where knowing the speed of a particular vehicle is critical. By tracking a specific target, Lidar systems can provide accurate and real-time speed measurements, differentiating between multiple vehicles in the vicinity and focusing on the one of interest, which is vital for assessing compliance with speed regulations or for accident investigations.

Other options, while related to the functionalities of Lidar, do not accurately describe the concept of target tracking. For instance, following stationary objects does not involve measurement of speed or movement, measuring speed of multiple objects simultaneously involves more complex data processing without a specific target focus, and detecting interference in the signal does not pertain to the tracking aspect of a vehicle's motion.
