Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
