Abstract
The MSTAR automatic target recognition (ATR) system recognizes targets by matching features predicted from a CAD model against features extracted from the unknown signature. In addition to generating signature features with high fidelity, the online Predictor in the MSTAR system must provide information that assists in efficient search of the hypothesis space as well as accounting for uncertainties in the prediction process. In this paper, we describe two capabilities implemented in the MSTAR Predictor to support this process. The first exploits the inherent traceback between predicted features and the CAD model that is integral to the predictor to enable component-wise scoring of candidate hypotheses. The second is the generation of probability density functions that characterize the fluctuation of amplitudes in the predicted signatures. The general approach for both of these is described, and example results are presented.
