Fundamental Limitations for DOA Estimation by a Sphere

Abstract
In this paper we consider fundamental limitations for DOA estimation with

arbitrary lossless antennas or antenna arrays inserted inside a sphere. Spherical

vector modes and their associated equivalent circuits and Q factor approximations

are employed as a general framework for the analysis. The

classical broadband matching theory by Fano is extended to a general multiport

S–parameter model of the antennas and fundamental bounds are given

for the scattering parameters with respect to bandwidth and electrical size

of the sphere. Finally, assuming a statistical signal model with Gaussian

receiver noise, the Cramer–Rao lower bound is used to derive fundamental
