The set of orthogonal eigen-vectors built via principal component analysis (PCA), while very effective for compression, can often lead to loss of crucial discriminative information in signals. In this work, we build a new basis set using synthetic aperture radar (SAR) target images via non-negative matrix approximations (NNMAs). Owing to the underlying… (More)
