Rescue Radar Transponder (SART) SAR-9

Rescue Radar Transponder (SART) SAR-9

SAR-9, 9 GHz Search & Rescue Radar Transponder (SART) is a self-contained, waterproof radar transponder intended for emergency use at sea. The radar-SART is used to locate a survival craft or distressed vessel by creating a series of dots on a rescuing ship’s radar display. A SART will only respond to a 9 GHz X-band (3 cm wavelength) radar. It will not be seen on S-band (10 cm) or other radar. Shipboard Global Maritime Distress Safety System (GMDSS) include one or more search and rescue locating devices.
