Paper Abstract

This paper describes a study that measured the performance of human image analysts in the surveillance context, using images from synthetic-aperture radar, in terms of the analyst's receiver operating characteristic (ROC) and an ancillary analysis of variance (ANOVA). The experiment was designed to correspond as closely as possible to an operational one for analysts using similar imagery. In particular, the effects of target contrast and background clutter on human analysts' target detection performance were quantified. Our ROC and ANOVA studies show that the clutter and contrast metrics used account for most of the variation in human performance as measured by probability of detection.
