Question 1 of 27070

Q

Frequencies generally used for marine RADAR are in the ___ part of the radio spectrum.

🔍 Key Concepts

• Marine radar frequency bands commonly used on commercial vessels (e.g., around 3 GHz and 9–10 GHz) • How the ITU radio spectrum is divided into named bands: VHF, UHF, SHF, EHF • Which named band covers frequencies in the gigahertz (GHz) range used by X‑band and S‑band radar

💭 Think About

• First, recall the approximate frequencies used by standard marine radars in GHz; then match those GHz values to the correct named band in the ITU table. • Think about which bands (VHF, UHF, SHF, EHF) are typically associated with voice communications vs. radar and microwave applications. • Eliminate any bands that are clearly too low or too high in frequency for typical marine radar systems.

✅ Before You Answer

• Know that typical marine radar operates at about 3 GHz (S‑band) and 9–10 GHz (X‑band). • Confirm which ITU band name corresponds to 3–30 GHz in the radio spectrum chart. • Make sure you do not pick a band that is normally associated with standard VHF marine radio (voice) frequencies around 156–162 MHz.
