This paper addresses the problem of passive wideband localization of a shallow water noise source in near-field with a horizontal array in the presence of multipath propagation. Multipath propagation gives rise to attenuated and time-delayed replicas of the original transmitted signal. The conventional beamforming approach to wideband localization involves the coherent signal-subspace method (CSM)...
Efficient and reliable operation is the main requirement of the modern power plant, hence it's significant that the boiler tube leakage source is localized precisely. The four-element acoustic array was exploited in the furnace, a set of hyperboloidal equations are established and the sensors distributed for capture the leakage signal is given. In order to avoiding initial guess and distant source...

The four-element acoustic array was exploited in the furnace and the schematic of sensors distributed for capture the leakage signal were given.

The method to determine the bearings of the three highlights sections of a ship based on a non-typical vector sound intensity array was proposed here. The array consists of 4 sensors that formed a spatial cross and the distances between the sensors can be changed. The bearing of the low frequency noise radiated by the midship and the middle part between the midship and stern is determined by sound...
