Challenge Problems
Push your limits with challenges.
Question 1
Given a radar system where SNR=15 dB and a desired Pfa of 10^-6, calculate the expected Pd using estimation techniques. Consider the trade-off scenario.
💡 Hint: Think back to the numerical examples in the text regarding SNR and Pd.
Question 2
If a radar system needs to minimize false alarms, how would you adjust thresholds while considering Pd and SNR? Provide a strategic approach.
💡 Hint: Reflect on how changing thresholds influences risk in radar performance.
