Question 991Navigation General

The correct answer is A) distance to a target. Radar is specifically designed to accurately measure the distance to a target by calculating the time it takes for the radar signal to travel to the target and back. This is known as the "range" or "distance" measurement. Radar is not as accurate in determining the size, shape, or direction of a target compared to its distance measurement capabilities. The other answer choices are incorrect because radar is not primarily used to determine the size (B), shape (C), or direction (D) of a target. These characteristics can be inferred to some degree from radar data, but the most precise measurement a radar system provides is the distance to the target.
