摘要 |
A method (500) for constructing a three-dimensional (3D) wave field representation of a 3D wave field using a two-dimensional (2D) sensor array (110), said method comprising: acquiring 3D wave field signals using a 2D array (110) of sensors (340, 350), said 2D array (110) of sensors (340, 350) comprising omnidirectional sensors (340) and first order sensors (350) arranged in a 2D plane; digitizing said acquired 3D wave field signals; computing even coefficients of spherical harmonics dependent upon said digitized 3D wave field signals acquired by said omnidirectional sensors (340); computing odd coefficients of said spherical harmonics dependent upon said digitized 3D wave field signals acquired by said first order sensors (350); and constructing a 3D wave field representation dependent upon said computed even and odd coefficients for said acquired 3D wave field signals. |
