Search Probability of Detection
Cumulative probability of detection across search passes.
Example
You enter
- Pod list 30, 40, 50
- POA (area contains subject, %) 60
You get
- Cumulative POD 79
- POS (probability of success) 47.4
Checked against published worked examples from: SAR search theory (Koopman) / National SAR Supplement.
Details, formula, and sources
Scopeprobability of success (POS = POA x cumulative POD), and residual containment probability for SAR planning.
Formula or tablecumulative_POD = 1 - product(1 - POD_i); POS = POA * cumulative_POD; residual = POA * (1 - cumulative_POD).
Source and editionStandard SAR search theory (Koopman detection theory) as used in the U.S. National SAR Supplement and NASAR / FEMA search-planning doctrine, by name.
