This report documents a literature survey of terrain-masking of ground targets. Target masking is defined and several definitions are given of the probability of unmask as a function of observer altitude and of the range from the observer to the target. Efforts to determine the probability of unmaks are divided into three categories 1 measurement of line of sight made directly on the terrain, 2 measurements of line of sight made on profiles constructed from topographic maps, and 3 predictions based on roughness characteristics of the terrain, such as average slope or standard deviation of altitudes. Available data are compared and evaluated. It is concluded that field measurement is the best way of determining target masking and that there is not nearly enough data accumulated to meet the need of users.
