| Abstract: | Based on the plane wave model of sound propagation, the direction finding formulas for a cross array and regular tetrahedron array are derived in a vector analysis method. And their various locating properties under the condition of the effective sound velocity variation are analyzed. The results obtained have shown that the application of an appropriate formular to the regular tetrahedron array can eliminate the inifluence of the effective sound velocity in acoustic direction estimation. |
