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 [...]

Calculating Probability Density Distribution for Missing Person Search
The first of the four elements of the optimal search problem is having a probability density distribution (predicting the likelihood that an object is in any particular search area or region.) To achieve this during a Maritime Search and Rescue Incident one takes into account the accuracy of the initial location report, the current, wind [...]

Elements of the Optimal Search Problem
Lawrence Stone defined the elements of the optimal search problem in his 1986 book, Theory of Optimal Search. This was paraphrased extremely well by Cooper, Frost and Robe in their 2003 report – Compatibility of Land SAR Procedures with Search Theory as quoted below; A probability density distribution on search object location and state (so [...]
