Abstract
The relationship between information capacity and the ability of photointerpreters to identify vehicles in simulated aerial reconnaissance was investigated. An aerial scene lighting simulator was constructed and used in the production of a series of simulated aerial reconnaissance photographs of models of military tanks and trucks. The information capacity of these photos was varied by defocussing the taking camera and the simulated ground scale was varied by changing the taking camera reduction. Duplicate positives of these images were evaluated by trained military photointerpreters who determined the resolving power and attempted to identify the vehicles from a key provided. The resulting empirical probability of correct identification for each vehicle was plotted against the information capacity, which was computed as one half the square of the resolving power. For a probability of correct identification of 0.80, these curves indicate that an information capacity of 7.4 bits per square meter on the ground is required to identify tanks, and 2 bits per square meter is required for identification of trucks.
