Abstract : This paper presents a result which implies that a horizontal rather than a vertical array design is best for estimating the source depth in an infinite homogeneous horizontal waveguide. Since a horizontal array configuration is best for estimating the source bearing, the same horizontal array can be processed to estimate depth. The optimal array depth, however, for bearing estimation can be different from the optimal array depth for source depth measurement. In order to present these results, the physics of the received signal must be considered.
