Challenge Problems
Push your limits with challenges.
Question 1
Given a radar system with SNR of 15 dB and a detection threshold set low, estimate the impact on both Pfa and Pd, and suggest an optimization strategy.
💡 Hint: Evaluate how rising and lowering thresholds impacts both metrics.
Question 2
Analyze a scenario where clutter significantly increases Pfa. Propose methods to mitigate this impact while maintaining Pd.
💡 Hint: Consider how adjustments can be made to deal with increased noise levels.
