🔍 Key Concepts

• Relationship between pulse repetition frequency (PRF) and maximum unambiguous range of a RADAR • Basic formula connecting speed of light, PRF, and range • Difference between Hz and kHz, and how that affects order of magnitude

💭 Think About

• Recall or look up the formula for maximum unambiguous range in terms of PRF. How does increasing PRF affect the maximum range before echoes become ambiguous? • Convert 100 nautical miles into meters (or kilometers), and use the speed of light to estimate what PRF would correspond to that range. • Compare your calculated PRF with the answer choices: are you looking for a relatively high or low PRF for long ranges?

✅ Before You Answer

• Make sure you use the correct form of the range–PRF formula and include the factor of 1/2 for the round-trip travel of the pulse. • Double-check your unit conversions: nautical miles to meters, and Hz to kHz. • Verify whether long-range operation requires a higher or lower PRF to avoid range ambiguities.
