What is the shape of the ROC curve dependent on?
💡 Hint: Think about what factor you control in a radar system.

Challenge Problems
Push your limits with advanced challenges
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.
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.
