Target recognition performance as a function of sampling

The effect of sampling, or aliasing, on target recognition performance (discriminating between armored tracked, armored wheeled, and soft wheeled classes of tactical vehicles) is investigated in this research. A recognition target set was processed with various levels of blur and aliasing. Integrated spurious response levels were set to 0, 0.3, 0.6, and 0.9. A perception experiment was conducted with U.S. Army soldiers at Ft. Benning, Georgia to determine the impact of blur and aliasing on recognition performance. The results are described in this paper.
