🔍 Key Concepts

• Racon (radar beacon) operation and purpose • Differences between 3 cm (X-band) and 10 cm (S-band) marine radar • How a racon appears on a radar display (range and clarity)

💭 Think About

• Think about which radar wavelength is more commonly used for navigation close to shore and buoys. • Consider the sensitivity and resolution of 3 cm vs 10 cm radar and which is better at picking up small objects and racon replies. • Ask yourself: Does a racon need a specific band to trigger, or can it respond to more than one, and what is most common in practice?

✅ Before You Answer

• Verify the typical frequency band (X-band vs S-band) that many coastal navigation aids are designed to respond to. • Check which radar type is usually used for detailed collision avoidance and buoy detection on most ships. • Confirm whether standard racons are usually tuned to one band or both bands in common practice.
