Challenge Problems
Push your limits with advanced challenges
Calculate the impact on Pd if the SNR is doubled while maintaining Pfa at 10^-6. Discuss the implications on a radar operator's decision.
💡 Hint: Look for the numerical values relating SNR improvements to changes in detection probabilities.
Provide a real-world scenario where balancing Pfa and Pd is crucial and discuss potential consequences of failing to do so.
💡 Hint: Use examples from defense or traffic control where alerts must be taken seriously.
