Hybrid Cram er-Rao bound of direction finding, using a triad of cardioid sensors that are perpendicularly oriented and spatially collocated
(Acoustical Society of America, 2019-07)
Cardioid microphones/hydrophones are highly directional acoustical sensors, which enjoy easy
availability via numerous commercial vendors for professional use. Collocating three such cardioids
in orthogonal orientation ...
Three-dimensional dislocations in a uniform linear array's isotropic sensors-Direction finding's hybrid Cramér-Rao bound
(Acoustical Society of America, 2020-05)
The linear array’sone-dimensional spatial geometry is simple but suffices forunivariate direction finding, i.e., isadequate for the estimation of an incident source’s direction-of-arrival relative to the linear ...
