How should the signal from a Search And Rescue Radar Transponder appear on a RADAR display?

Explanation:
On a radar screen, a Search And Rescue Radar Transponder signal shows up as a ring of dots: specifically twelve equally spaced dots forming a circle around the target. This distinctive pattern is produced by the transponder when interrogated and makes the distressed vessel easily identifiable to the radar operator, helping determine its location as the radar sweeps. Other shapes or symbols, like a single circular beacon, a flashing square, or numbers, don’t match how SART responses appear on radar and wouldn’t provide that recognizable dot-ring pattern.
