SART is life-saving equipment that was approved by GMDSS and is used for detecting positions of 
survivors who suffer from distress accidents. SART, which operates under the frequency band of 9GHz, 
receives  a radar wave of 9GHz that is launched from the radar of the rescue boat or plane and 
generates a series of response signals to notify the accident position to the searchers.
