... the localization accuracy of the search. Localization accuracy is defined in terms of the area of intersection of the sensor spatial-temporal coverage regions as seen from the target frame of reference. ... measure of localization accuracy is the area of uncertainty, which identifies a region of the search space S where the target is located. Often, the area of uncertain...
