What is the detection range of the Sentinel A3 radar?

• A. 20 km
• B. 40 km
• C. 60 km
• D. 75 km

Answer: (B)

Radar detection range is set by how far the radar can reliably spot a target given its size, altitude, the system’s power and sensitivity, and the antenna design. The Sentinel A3 is a mobile, mid-range 3D surveillance radar optimized for timely detection of air targets at moderate distances. For typical aircraft at standard flight altitudes with ordinary radar cross sections, its practical detection range is about 40 kilometers. This makes it well-suited to quickly cue shorter-range air defenses and provide continuous tracking in dynamic, mobile operations. While larger or higher-altitude targets can sometimes be detected farther, the A3’s published performance aligns with roughly 40 km as its standard detection range. Ranges like 20 km are shorter than its typical capability, and 60 or 75 km reflect longer-range systems rather than this mobile, mid-range radar.
