Q

An S-band RADAR operates in which frequency band?

🔍 Key Concepts

• Marine RADAR frequency bands used on merchant and fishing vessels • Difference between S-band and X-band RADAR in terms of wavelength and weather performance • Relationship between frequency (GHz) and wavelength (cm)

💭 Think About

• Think about which RADAR band (S or X) is known for better performance in heavy rain, sea clutter, and poor visibility and how that relates to its wavelength. • Recall the approximate wavelength range for S‑band RADAR and then convert that to the corresponding frequency range in GHz. • Compare each answer choice with what you remember about typical X‑band RADAR frequencies and eliminate the one that matches X‑band.

✅ Before You Answer

• Verify which frequency range is commonly associated with X‑band marine RADAR and eliminate that choice. • Check that the remaining range corresponds to a longer wavelength (around 10 cm) typical of S‑band. • Confirm that the chosen frequency band is the one typically installed on ships for long‑range, poor‑weather detection.
