What is a primary function of Sentinel radar?

• A. Weather forecasting
• B. Detecting, tracking, classifying, and identifying air threats and providing targeting data.
• C. Oceanic mapping
• D. Ground target designation

Answer: (B)

Sentinel radar is built to support air defense by handling the full sensor-to-engagement process for airborne threats. It detects incoming air targets such as aircraft, missiles, and drones, then tracks them to maintain an accurate sense of their position and motion. It classifies each target to determine its type, and it identifies targets to distinguish threats from non-threats and to understand what kind of engagement might be required. Crucially, it generates targeting data—range, bearing, altitude, and velocity—so fire-control systems can accurately cue interceptors or guns. Weather forecasting and oceanic mapping use different sensing goals, and ground target designation is oriented toward surface targets, not air threats. The combination of detecting, tracking, classifying, identifying, and providing targeting data is what makes Sentinel effective for rapid air-defense engagement.
