A PRELIMINARY COMPARISON OF LASERS WITH PHOTOGRAPHY FOR FINDING TACTICAL TARGETS.
Abstract
Six photographic transparencies of a simulated jungle area containing a variety of model tactical targets including trucks, aircraft, artillery, etc., were tested on their relative value for near-real-time reconnaissance. Two of the transparencies, high resolution black-and-white and color photography, are representative of a good daylight tactical reconnaissance capability. The remaining four transparencies were made with experimental multispectral laser night sensor systems. Each transparency was projected onto a translucent screen (9.7 inches high by 18 inches wide) for a period of two minutes and the test subject asked to locate the tactical targets. There were eight subjects per transparency with a total of 48 subjects tested. For the entire two minute viewing time the number of targets detected and the accuracy of responses were not significantly different among the six transparencies. On the average, targets were found more rapidly on the black-and-white photographic transparency than on the color photographic transparency but this slight advantage did not hold up for the groups with the transparencies made with the night sensors. For the first 30 seconds viewing time the black-and-white photo group was superior on number of target detections and detection time, with some of the night sensor transparencies equal to the color photography on these performance measures. All six groups were essentially equal in accuracy during the first 30 seconds of exposure to the transparencies. (Author)
