Ranging

Ranging is a process used by devices like radar, sonar, or GPS to determine the distance to an object. It works by sending out a signal (such as a radio wave or sound wave), which travels to the object and then bounces back. By measuring the time it takes for the signal to return, the device can calculate how far away the object is. This technique helps in navigation, object detection, and measurement tasks, providing precise distance information essential for various applications like aviation, maritime, and automotive systems.
