How many radar blips does a SART emit on a ship's radar along its line of bearing?

• A. 8 blips
• B. 12 blips
• C. 16 blips
• D. 24 blips

Answer: (B)

A SART replies to radar interrogation with a fixed, recognizable pattern: a string of blips that sits along the line of bearing to the beacon. The standard response is 12 blips. This consistent sequence makes the SART easy to identify on a ship’s radar and helps the operator gauge direction toward the beacon quickly. The 12-blip pattern is chosen to provide a clear, unambiguous signature that stands out on the radar display, whereas the other counts don’t match the established pattern used for SART responses.
