Which type of radar is designed to provide positional data on a target?

Tracking radar is specifically designed to continuously monitor and determine the position of a target over time. Its primary function is to provide accurate positional data, enabling operators to follow the trajectory or movements of a target. This type of radar continuously processes and updates information about the target's location, speed, and direction, which is crucial for various applications, including air traffic control, maritime navigation, and military operations.

The other types of radar mentioned serve different purposes. For instance, missile guidance radar is focused on providing the guidance necessary for a missile to reach its target instead of tracking its position continuously. Surface search radar is generally used for detecting objects on or near the water's surface, and while it can provide some information about positional data, its primary function is not tracking but rather searching and detecting. Approach radar assists in guiding aircraft during final approach for landing but is not typically designed for continuous tracking across greater distances.
