Paper Abstract

This paper presents a three-dimensional (3-D) receiver operating characteristic (ROC) trajectory which combines the principles of the standard ROC curve used in automatic target recognition (ATR) with a third performance measure. These 3-D ROC trajectories are used to compare competing target recognition algorithms when unknown targets are present in the data. A probability of rejection is added to the standard ROC curve that includes the probability of successful detection (true positive rate) and the probability of false alarm (false positive rate). By using the probability of rejection, targets may be eliminated that are difficult to classify, or perhaps unknown. The 3-D ROC trajectory can be a useful tool for a SAR image analyst for understanding the tradeoffs between the probability of rejection and the two standard performance measures commonly used in detection problems.
