🔍 Key Concepts

• SART (Search and Rescue Transponder) operating frequency and purpose • Differences between X-band and S-band radar on ships • Which equipment is specifically designed to trigger and display a SART radar echo pattern

💭 Think About

• Ask yourself: A SART is activated by being illuminated by what type of ship’s radar? • Which radar band is commonly used for navigation and detecting small targets like buoys and SARTs? • Do DSC receivers or autoalarms display radar echo patterns, or do they handle a different part of distress alerting?

✅ Before You Answer

• Verify the frequency band that a SART responds to under GMDSS requirements. • Check which radar type (X-band vs S-band) is better at detecting small targets at short range. • Confirm that DSC (Digital Selective Calling) and autoalarm deal with radio/telex alerts, not radar echo displays.
