Q

What is the relationship between pulse repetition rate and pulse width?

🔍 Key Concepts

• Pulse repetition rate (PRR) in radar and how it affects the time between transmitted pulses • Pulse width and how it affects the duration of each pulse and the maximum unambiguous range • How energy is distributed when you change one parameter while trying to maintain practical radar performance

💭 Think About

• If you make each pulse wider (longer in time), what must usually happen to the spacing between pulses to avoid overlap of echoes from one pulse with the next? • Think about maximum unambiguous range: do you want long listening times or short listening times between pulses, and how does that relate to PRR? • In a practical radar, can you keep increasing both PRR and pulse width without causing range-ambiguity problems?

✅ Before You Answer

• Be clear on the difference between time between pulses (related to PRR) and duration of a single pulse (pulse width). • Consider whether they can be increased independently in a real radar without causing overlapping returns or loss of target discrimination. • Check which options describe a direct vs inverse relationship between PRR and pulse width.
