Question 1 of 27070

Q

RADAR receivers are similar to:

🔍 Key Concepts

• RADAR frequencies used in marine applications (e.g., X-band and S-band) • General part of the radio spectrum where RADAR operates (centimeter wavelengths) • What type of receiver is normally used at very high frequencies and above (VHF, UHF, SHF)

💭 Think About

• Think about which type of receiver is designed to work in the same frequency range as typical marine radar (around 3 GHz and 9 GHz). • Consider which option names a receiver type associated with very short wavelengths (centimeters) rather than meters. • Ask yourself: which of these choices is commonly associated with super high frequency radio and line-of-sight propagation, like RADAR?

✅ Before You Answer

• Verify which band of the spectrum marine RADAR usually operates in (e.g., S‑band and X‑band, in the GHz range). • Check which choice is explicitly linked with very high / ultra high / super high frequency and short wavelengths. • Eliminate any receiver types that are typically used for audio broadcasting or lower‑frequency communication rather than for GHz-range signals.
