Lesson 8 — Detection Theory

Where the minimum detectable signal actually comes from — the noise floor, the detection threshold, and the \(P_d/P_{fa}\) tradeoff read off a ROC curve — plus the integration gain that turns a longer dwell into a longer range and closes the loop on the L3 range equation.

Reading

Detection Theory

Noise floor, SNR and the threshold, the ROC curve, coherent vs non-coherent integration, and \(S_{\min}\) as a contract.
