What does SART stand for?

SART stands for Search and Rescue Transponder. This is a crucial piece of equipment used in maritime operations, primarily to assist in search and rescue missions. When activated, a SART responds to radar signals from nearby vessels or aircraft by transmitting its own signal, which appears as a series of distinct marks on radar screens. This makes it much easier for rescuers to locate the distressed vessel or individual in need of assistance.

Understanding the function and importance of SART is vital for maritime safety and operations, as it significantly enhances the effectiveness of search and rescue efforts. The other options, while reflecting terms that might seem plausible in the context of rescue operations, do not correspond to the commonly recognized acronym SART used in maritime responses.
