Abstract

In this study, the conventional beamforming (CBF) and the minimum variance distortionless response (MVDR) beamforming with a line hydrophone array mounted on an infinite rigid cylindrical baffle are proposed. Based on decomposing the sound field into a summation of harmonics, a model is introduced to compute the noise cross-spectral matrix in the spherically isotropic noise field. Some design examples are given with different array configurations and different kinds of incident signals. In comparison with the acoustically transparent array, the effects of the baffle scatter on the array gain and white noise gain are examined. Simulation results show that the baffled array has an advantage over the transparent array in a wide range of elevation angles.
