In this study, a new method for designing a volumetric V-shaped sensor array is proposed, which has isotropic elevation and azimuth Direction of Arrival (DOA) angle. The proposed method optimizes the angles between linear sub-arrays and planes of the two V-shaped sensor arrays to be isotropic. Optimization of the angles is done by using the Cramer-Rao Bound (CRB), which accounts for the statistical coupling effect of elevation and azimuth angle estimation. The designed 3-D V-shaped sensor array is compared with different planar array.
