Calculating Probability of Detection in Search and Rescue
I wrote a couple of weeks ago about how to calculate a probability density distribution for a missing person search. This was the first element of the optimal search problem. The second element is to be able to calculate the probability of detection. There have been numerous articles and methodologies proposed in the past. Most [...]

Coverage
Coverage as a word is often used to describe how much of a search area or sector has been searched. This is wrong. Coverage has a specific mathematical definition in search theory. It refers to the Area Effectively Swept divided by the Area of the Search Sector. Â This figure is then used in Koopman’s Exponential [...]

Probability of Detection (POD)
Probability of Detection refers to the likelihood of a search resource finding the object they are searching for if it was in the area they were searching. Thanks to Koester, Cooper, Frost and Robe’s 2004 study we can now safely say that it is impossible to subjectively estimate POD. No more should we hear supposed Search Managers [...]
