The process of air to ground targeting for military attack aircraft involves three distinct, sequential phases of visual discrimination: detection, recognition, and identification (DRI). The intent of this paper is to discuss the tactical merits of charged coupled device (CCD) technology in air to ground target DRI, while contrasting the limitations imposed by the loss of direct view optics (DVO). During an extensive flight and ground test program conducted at the Naval Air Warfare Center Aircraft Division, Patuxent River, MD, an experimental airborne electo-optical targeting sensor suite featuring high resolution CCD cameras was evaluated by direct comparison to an existing system based on DVO. The results indicated superior performance of the CCD cameras in low ambient lighting conditions, but the absence of color was a major hindrance to rapid target area acquisition. Test results indicated that high resolution and magnification are not the most critical design criteria for an airborne electo-optical targeting suite; human factors must influence the design based upon a thorough, systematic analysis conducted during flight test.
