How should the signal from a Search And Rescue RADAR Transponder appear on a radar screen?

A Search and Rescue Transponder’s radar response is shown on the radar display as a string of 12 equally spaced dots. This distinctive dotted pattern comes from the SART’s pulsed reply to radar interrogations, and it’s trained operators to recognize quickly so they can identify the distress beacon and determine its bearing and approximate range. The other patterns described—dashes, spirals, or a larger number of dashes—do not match how a SART appears, so the 12-dot sequence is the correct signature you should look for.
