Terrain scene classification plays an important role in various synthetic aperture radar (SAR) image understanding and interpretation. This paper presents a novel approach to characterize SAR image content by addressing category with a limited number of labeled samples. In the proposed approach, each SAR image patch is characterize by a discriminant feature which is generated in a semisupervised manner by utilizing a spare ensemble learning procedure. In particular, a nonnegative sparse coding procedure is applied on the given SAR image patch set to generate the feature descriptors first. The set is combined with a limited number of labeled SAR image patches and an abundant number of unlabeled ones. Then, a semisupervised sampling approach is proposed to construct a set of weak learners, in which each one is modeled by a logistic regression procedure. The discriminant information can be introduced by projecting SAR image patch on each weak learner. Finally, the features of SAR image patches are produced by a sparse ensemble procedure which can reduce the redundancy of multiple weak learners. Experimental results show that the proposed discriminant feature learning approach can achieve a higher classification accuracy than several state-of-the-art approaches.
