🔍 Key Concepts

• Speed of radio waves in nautical miles per second (same as speed of light) • Relationship between pulse repetition frequency (PRF) and range ring spacing • Conversion of 0.25 nautical miles to the time a radar pulse needs to go out and come back

💭 Think About

• How long (in seconds) does it take for a radar pulse to travel 0.25 nautical miles out and 0.25 nautical miles back? • Once you know the round-trip time for 0.25 NM, what frequency (1 / time) does that correspond to in cycles per second (Hz)? • After you find the frequency in Hz, how do you convert it correctly into kilohertz (kHz) and compare it to the answer choices?

✅ Before You Answer

• Use the correct speed of radio waves in NM/second (approximately 162,000 NM per second) • Remember the pulse must travel out and back (round trip distance is 0.5 NM for a 0.25 NM ring spacing) • Double-check your unit conversions from seconds to Hz to kHz before matching with the choices
