Which statement is true regarding the SART?

• A. This is a 9GHz transponder capable of being received by vessel's X-band navigational RADAR system.
• B. This is a 3GHz transponder.
• C. It can only be received by shore radar.
• D. It transmits voice calls.

Answer: (A)

A SART is a radar transponder that helps rescuers locate a distressed vessel by responding to radar interrogations. It operates in the 9 GHz range, which is the X-band used by most maritime navigational radars, and when a radar signal interrogates it, the SART transmits back a radar response that appears on the interrogating ship’s display as a line of dots. This makes it easy to determine range and bearing to the distress source. It is not a 3 GHz device, it is not limited to shore radar, and it does not transmit voice calls—only radar signals. So the statement that it is a 9 GHz transponder capable of being received by a vessel’s X-band navigational radar is the correct description.
