Multichannel Broadband Fano Theory with Applications in Array Signal Processing

Nordebo, Sven LU and Gustafsson, Mats LU orcid (2005) Foundations of Propability and Physics 3 750. p.288-297
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 lower bounds for the performance of DOA estimation by a sphere.
