Search and Rescue Radar Transponder (SART)

THE MAIN TECHNICAL CHARACTERISTICS

The SART transmits a signal over a swept band in the 9 GHz range (X Band) which appears as a straight line of ‘blips’ on the radar screen.

SARTs may be packed in a life raft, incorporated in a float-free EPIRB or mounted in a float-free housing eg. above a ship's bridge. The SART may be switched on manually or automatically if immersed in water (eg. when incorporated in a VHF DSC EPIRB).

After switch-on the SART will remain in standby mode (for up to 96 hours) until a radar transmission in the 9 GHz range, from ship or aircraft, triggers a response. When this occurs, transmission from the SART appears as a perfectly straight line of twelve ‘blips’ (radiating ...
