Abstract

Acoustic source localization (ASL) on a thin isotropic spherical shell is more challenging than that for two-dimensional flat plate structures. Here, a localization technique for isotropic spherical shell is proposed based on the triangular time difference using only four sensors without knowing the acoustic wave speed in the material. The proposed technique does not require solving a system of nonlinear equations, thus it greatly reduces the complexity of calculation. A finite element model of a thin isotropic spherical shell was created to verify the proposed acoustic source localization technique. The results of numerical simulation prove the reliability of the proposed technique.
