What is the purpose of tracking radar?

Tracking radar serves a critical role in maintaining constant surveillance of detected targets. Its primary function is to monitor the movement of objects within its range over time, allowing operators to keep tabs on the position and speed of various targets, whether they are aircraft, ships, or other entities. By continuously assessing the position of a target, tracking radar enhances situational awareness and helps in making informed decisions regarding defense strategies and operational safety.

The other options, while relevant to different types of radar or maritime operations, do not capture the primary purpose of tracking radar specifically. For instance, confirming the identity of friendly vessels is more closely related to identification friend or foe (IFF) systems, locating underwater mines relates to sonar systems, and measuring the speed of projectiles typically involves other specialized equipment like speed sensors or ballistic tracking systems. Thus, the emphasis of tracking radar is firmly on sustained observation and engagement with moving targets.
