🔍 Key Concepts

• Pulse Repetition Frequency (PRF) and how it relates to maximum unambiguous range • Relationship between time for one pulse to travel out and back and radar range • Speed of radio waves (speed of light) in meters per second and conversion to nautical miles

💭 Think About

• First, think about how long it takes for a radar pulse to go out to 30 nautical miles and return. What distance is that in total, and how does that relate to time? • Once you have the round-trip time for 30 NM, ask yourself: How many such pulses could you send in one second without getting echoes mixed up from different pulses? • Compare that maximum pulses-per-second value with the units used in the answer choices (Hz vs kHz). Which choices are clearly too high or too low?

✅ Before You Answer

• Convert 30 nautical miles to meters or kilometers and then to total round-trip distance. • Use the speed of light (about 3 × 10^8 m/s) to find the round-trip time for that distance. • From that time, compute the corresponding maximum PRF (1 / time) and check which answers are in the right order of magnitude (Hz vs kHz).
