Question 1
What is the shape of the ROC curve dependent on?
- Detection Threshold
- Receiver Speed
- Signal Strength
💡 Hint: Think about what factor you control in a radar system.
Question 2
True or False: An ROC curve's position provides insights into the trade-off between Pd and Pfa.
- True
- False
💡 Hint: Recall what the ROC curve represents.

Challenge Problems
Push your limits with challenges.
Question 1
You have two radar systems: System A has an ROC curve that hits a Pd of 0.95 at Pfa = 0.01, while System B peaks at Pd = 0.85 for the same Pfa. Determine which system would be preferable in a critical surveillance task and explain why.
💡 Hint: Compare the performance of both systems side by side.
Question 2
Consider a system with a detection threshold that has been set too high, resulting in a low Pd but an acceptably low Pfa. How might you adjust the threshold to improve overall performance without drastically increasing false alarms?
💡 Hint: Think strategically about threshold adjustments.
