The SART can either be stowed in a life raft, or mounted next to emergency exits and then carried to the life raft in an emergency. During an emergency, simply switch the SART on. When a vessel or aircraft with marine X-band Radar comes within 5 to 7 nautical miles of the life raft, the SART generates a distinctive “distress” pattern on the Radar screen (See figure 1). The radar signal guides the rescuers directly to the SART. Text Box: Radar Screen Figure 1 Text Box: SART Location Text Box: Radar Distress Pattern 2.0 Introduction The SART is a Search and Rescue Transponder that provides location information to search radars operating in the X-band (9.2 – 9.5 GHz). Once activated the SART detects the radar signal of the search craft and sends a series of response pulses to the radar of the search craft that causes a series of 12 equally spaced arcs to appear on the radar display (see figure 1). The arcs indicate the direction to the SART location. The rescue craft follows the direction shown and proceeds to the SART. To achieve the maximum useful range the SART must be mounted at least 3.3 feet (1 meter) above sea level. Increasing the height of the SART antenna will increase the range. For example, lashing the SART to the top of a pole or an oar in the survival craft will increas...
