Challenge Problems
Push your limits with challenges.
Question 1
A radar detects signals with a Pfa set at 0.01. If the receiver identifies a target but noise is the actual source, calculate the Type I error rate.
💡 Hint: Consider how often a radar falsely identifies noise as a target.
Question 2
If a radar system is set to a very low Pfa of 0.001 but misses 5 out of 10 actual targets detected due to high noise, what implications might arise?
💡 Hint: Assess whether the radar's settings balance sensitivity well enough.
