An Examination of SAR Image Interpretation Aids: Magnification and an Information Window

Abstract

This study examined the image interpretation performance of Synthetic Aperture Radar (SAR) imagery analysts on images that contained Assisted Target Recognition (ATR) designations. The purposes of the study were: 1) to compare the performance of the analysts using one of two magnification methods, a moving magnifier (simulated magnifying glass), or a magnification window at the side of the display; 2) to examine the benefit of adding an information window at the side of the display which included an optical image, a SAR image, and sketches of the vehicles used in the study. These two purposes were combined in the study's design. The design consisted of two parts: in the first part, 25 analysts interpreted 72 images; and in the second part, the eye-movements of 9 analysts were monitored as they carried out the same task.
