The Patriot Radar does what three functions to targets?

• A. Detects, tracks, identifies
• B. Detects, tracks, measures
• C. Detects, identifies, tracks
• D. Detects, tracks, locks

Answer: (A)

The Patriot radar performs three core functions for each target: detect its presence, track its flight path, and identify whether it is friend or foe. Detection is about picking up a radar return from a passing object. Tracking then uses successive detections to maintain a continuous picture of the target’s position and motion, providing range, bearing, and altitude updates for fire control. Identification is done through IFF—the radar interrogates friendly transponders and reads their replies to classify the target and avoid engaging allies. The other terms like measuring or locking aren’t the standard trio of radar functions in this system, so detection, tracking, and identification best describe what the radar does.
