Learning Strategies for Radar Clutter Classification [PDF]
IEEE Transactions on Signal Processing, 2021 In this paper, we address the problem of classifying clutter returns in order to partition them into statistically homogeneous subsets. The classification procedure relies on a model for the observables including latent variables that is solved by the expectation-maximization algorithm.
