| Popis: | The cross‐sensor field of an array consists of all products of the narrow‐band quadrature signal measured at one sensor multiplied by the complex conjugate of the quadrature signal measured at a second sensor. Three algorithms which use the cross‐sensor field to determine the level and direction of a set of acoustic waves incident on a billboard array are compared. These are correlation (conventional) beamforming, maximum likelihood estimation, and iterative decomposition. |
