Abstract

Statistical and neural network approaches to the classification process of automatic target recognition (ATR) with a synthetic aperture radar (SAR) imaging mode for four ground vehicles are investigated and their performance compared. A set of image features is extracted from a training set of SAR images. A subset of these image features is selected which maximizes the likelihood of correct classification assuming a Gaussian feature distribution. An improved method for statistical classification is demonstrated in which training data is selected based on its statistical variation with azimuth angle. With proper selection of image features it is shown that the misclassification rates of both the statistical and neural network classifiers are approximately the same.
