🔍 Key Concepts

• Maximum unambiguous range of a radar in relation to PRF (pulse repetition frequency) • Relationship between PRF and pulse repetition period (PRT): PRF = 1 / PRT • The time it takes for a radar pulse to travel to the target and back at the speed of light

💭 Think About

• How does increasing PRF affect the maximum unambiguous range of the radar? Think about whether a higher PRF gives the pulse enough time to go out and return before the next pulse is transmitted. • Convert a PRF in Hz to a pulse repetition period (PRT) in seconds or microseconds. Then ask: is that enough time for a pulse to travel to 10 NM and back at the speed of light? • Which of the choices is not a frequency, and what common radar timing quantity might it represent instead?

✅ Before You Answer

• Compute the round-trip distance for 10 NM and convert it to meters, then calculate the time needed for a pulse to travel that distance at roughly 3×10^8 m/s. • For each frequency choice, convert between PRF (Hz or kHz) and PRT (seconds or microseconds) and see which timing makes physical sense for a 10 NM maximum range. • Be sure you are not mixing up frequency (Hz or kHz) with time (seconds or microseconds) when comparing the answer choices.
