Array-based underwater acoustic target classification with spectrum reconstruction based on joint sparsity and frequency shift invariant feature
The target spectrum, which is commonly used in feature extraction for underwater acoustic target classification, can be improperly recovered via conventional beamformer (CBF) owing to its frequency-variant spatial response and lead to degraded classification performance. In this paper, we propose a...
