Resumo: Passive sonar systems used in submarines, performs the direction of arrival (DOA), the detection and classification of targets signals that are impinging on the hydrophones from a particular direction of interest. In some situations, depending on the resolution of the beamformer (hydrophones array) and when the signals are at too close bearings, a cross interference may bring difficult on the target identification by the operator of sonar. This paper aims at using independent component analysis (ICA) as preprocessing on DEMON analysis to improve the targets identification.The FastICA algorithm was used, which was applied to the simulated data, and performance was measured both, qualitatively and quantitatively.
