dc.description.abstract | Underwater sound source position is determined using a line array like the TASS, frank array using the beamforming and band analysis. However, performance degradation occurs owing to a multipath environment, which generates incoherent signals. In this paper, a hydrophone array is proposed for underwater source position estimation robust to a multipath environment. For verification of the proposed array, we perform experimental analysis with the conventional array. The proposed system is not affected by a multipath time delay because of the close distance between closely spaced sensors. The array is composed of three pairs of sensors that are a coupled of closely-spaced hydrophone placed on the same line. The source position is estimated by performing generalized cross-correlation (GCC) and wavefront curvature analysis. The validity of the array is confirmed by experiment.ls.
