Automatic Target Recognition Display Format Study

Abstract

In the foreseeable future, automatic target recognition (ATR) systems are going to become an integral part of targeting systems. How these ATRs interact with operators is clearly going to influence overall system accuracy. The objective of the two studies covered by this report was to explore the effect of two specific ATR-operator interface factors on identification accuracy. The two factors were the number of recommendations the ATR provides the operator and the nature of the accuracy measure figure of merit, (FOM) provided with each recommendation. A simulated range only radar (ROR) task was used to explore the effect of these two factors. Two levels (1 and 5) were used for the number of recommendations and three levels (qualitative, quantitative, and none) were used for the accuracy measure. The effect of these factors was investigated under two levels of ATR and operator accuracy, nominally 80 and 40%, respectively. These factors influenced both the likelihood that an operator would alter a correct ATR recommendation and the likelihood that an operator would correct an incorrect ATR recommendation. The influence was greater in the former than in the latter. Increasing the number of recommendations significantly increased the likelihood that an operator would disagree with the ATR's first recommendation, regardless of whether this first recommendation was correct. The type of FOM used had only a small effect when associated with a single recommendation. However when paired with five recommendations, subjects were less likely to disagree with a recommended identification if a quantitative FOM was provided.
