Question 1 of 27070

What pulse width and repetition rate should you use at long ranges?

🔍 Key Concepts

• Radar pulse width effects on maximum range and target resolution • Pulse repetition rate (PRR) / pulse repetition frequency (PRF) effects on long-range detection • Trade-off between seeing distant weak echoes vs. fine range discrimination

💭 Think About

• For very long ranges, do you care more about detecting weak, distant targets or about very fine discrimination between two close targets? • How does increasing pulse energy (by changing pulse width) affect how far the radar can "reach" before the echo becomes too weak? • What happens to maximum unambiguous range when you increase the pulse repetition rate?

✅ Before You Answer

• Recall which pulse width provides more energy per pulse and thus better long-range detection. • Recall how high vs. low repetition rate affects maximum unambiguous range. • Match the option that best supports detecting far targets and avoiding range ambiguity at long ranges.
