摘要：
In novel underwater wireless sensor array network architecture (UWSAN), each sensor node is attached to a local sensor array which performs maximum likelihood direction of arrival (DOA) locally. Sensor nodes communicate via acoustic channel and exchange DOA estimate and received target signal energy. Global DOA based localization is combined with energy in a non-linear least square cost function to realize multi-modal target localization. Very promising simulation results demonstrated preliminarily the feasibility of such a new approach for underwater wireless sensor network.
