Abstract
Underwater sound source position is determined using a line array. However, performance degradation occurs owing to a multipath environment, which generates incoherent signals. For this reason, the system needs advanced signal processing such as high-resolution beamforming. In this paper, a hydrophone array is proposed for position estimation robust to a multipath environment using generalized cross-correlation(GCC). The array is composed of three pairs of sensors placed on the same line. The proposed system is not affected by a multipath propagation because of the close distance between closely spaced sensors. The validity of the array is confirmed by experiment performed in water tank and simulation using acoustic signals synthesized by eigenrays.ch as high-resolution beamforming.
