Final Report on the Optimal Placement of Military Targets in Cluttered Terrains.

Abstract

This experimental program investigated the optimal placement of military targets in cluttered terrains. Three experimental areas were explored. The first area involved an embedded target search display. The discriminability of targets in this display was measured in three ways: (1) by reducing viewing time, (2) by blurring the observer's view of the display, and (3) by reducing transmissivity. A competition search situation was investigated in the second experimental area; the optical blur measure of discriminability was used. Visual search behavior was directly investigated in the third series of experiments. The findings were as follows: (1) search was slower when two areas of a given clutter density had to be searched than when a single area was searched; (2) compared to an isolated search area, the presence of an adjacent, similarly cluttered nonsearched area may result in search being slower; and (3) the presence of different clutter densities in a nonsearched area resulted in different search time distributions for search in an adjacent area. The data from these various experiments will help in characterizing the relation between a target and its detectability. Such work in perception is a necessary step toward the development of camouflage standards for the prime visual threat.
