🔍 Key Concepts

• Pulse width (PW) determines minimum range and range resolution of the radar • Pulse repetition rate (PRR or pps) must be low enough that echoes from the farthest range return before the next pulse is sent • The relationship between maximum unambiguous range and pulse repetition rate

💭 Think About

• On a 1.5 mile range, do you need very long pulses or relatively short pulses to separate closely spaced targets near your own ship? • If the radar can show out to at least 1.5 miles, should the pulse repetition rate be very high or moderate so that the echo from the farthest target returns before the next pulse? • Which combination of PW and pps seems appropriate for a short-range scale rather than for long-range search?

✅ Before You Answer

• Recall that shorter pulse width improves close-range resolution but reduces energy in each pulse • Check that the PRR (pps) is not so high that an echo from 1.5 miles could arrive after the next pulse has already been transmitted • Eliminate any option whose pulse width looks more suitable for long-range operation instead of a 1.5 mile scale
