Question 1

What represents the null hypothesis in radar detection?

Only noise is present
A target is detected
Both noise and target are present

💡 Hint: Think about what the baseline scenario is.

Question 2

Type I error refers to:

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
