Abstract: A method for determining a path of travel of an intruder traversing an area of regard (AOR) to a predefined point, where the path of travel has a minimum probability of detection relative to other potential paths of travel of the intruder. The method may comprise: providing three dimensional terrain data concerning the AOR; providing the locations of a plurality of detection sensors implemented in the AOR, with each detection sensor having a known field of view; providing a predetermined single scan detection probability for each of the detection sensors; generating a grid of points that is laid over the AOR; and using the foregoing information to determine a particular path of travel, defined by selected arcs connecting specific ones of the grid of points, of the intruder to the predefined point that represents a minimum probability of detection of the intruder.
