For surface ships, the towed hydrophones array is usually used to detect azimuth and to track moving targets because of its large aperture. The effective scope of a common sound pressure single array is only 180°, so that the common array cannot determine whether a target is to the left or to the right. While a twin-line array has similarity with a planar array in theory, a twin-line array does have...
Focused beamforming technology is a high precision passive localization algorithm which is mostly applied in near field. In this algorithm, the received signal is compensated by spherical wave based on different direction and distance in the measurement area in order to obtain the spatial distribution of noise sources. This technology can be used to detect noise distribution of ships and some engines,...
