Underwater source localization in the presence of strong interference

Underwater source localization in the presence of strong interference

Abstract The underwater localization of a broadband target in the presence of strong interference and noise has been widely investigated. A novel clutter suppression approach based on oblique projections is proposed, exploiting the prior information of the expected target response. The method uses a...
