Q

What is the normal range of pulse repetition rates?

🔍 Key Concepts

• Pulse Repetition Rate (PRR) in marine radar (measured in pulses per second, pps) • Relationship between maximum range and how fast you can send out pulses • Difference between very low, normal, and very high PRR values

💭 Think About

• Think about why you cannot make the pulse repetition rate too high if you want to see long ranges on radar. • Compare each range of values and ask: Which looks more like a "middle" or normal operating range rather than an extreme low or extreme high? • Consider that typical marine radars must work well from short to fairly long ranges. What approximate pps band would accommodate both?

✅ Before You Answer

• Eliminate any option that seems too high to allow echoes from long range targets to return before the next pulse is sent. • Eliminate any option that seems too narrow to represent a usable adjustment range on a practical shipboard radar. • Ask which option best represents a moderate band of pps values commonly used in general-purpose marine radar, not a special-purpose system.
