🔍 Key Concepts

• SART (Search and Rescue Transponder) operating principle • Difference between continuous transmission vs replying to interrogation • How a SART interacts with X-band radar (9 GHz) on nearby vessels

💭 Think About

• Think about whether a SART is meant to transmit all the time, or only when another device "wakes it up." • Ask yourself: does the SART create its own signal on its own, or does it wait for a ships radar pulse first? • Consider how conserving battery power in an emergency device might affect when it actually radiates a signal.

✅ Before You Answer

• Verify whether a SART sends out energy only after detecting a specific radar frequency pulse. • Check if water contact alone is enough to make a SART start radiating, or if another condition is required. • Confirm if an operator needs to keep keying it, or if once armed it works automatically in response to radar.
