Rules-of-thumb to design a uniform spherical array for direction finding—Its Cramér– Rao bounds' nonlinear dependence on the number of sensors
(Acoustical Society of America, 2019-02)
ABSTRACT
This paper discovers rules-of-thumb on how the estimation precision for an incident source's azimuth-polar direction-of-arrival (ϕ,θ) depends on the number (L) of identical isotropic sensors spaced uniformly on ...
