Performance analysis of ESPRIT and TAM in determining the direction of arrival of plane waves in noise
Abstract
The authors evaluate two subspace-based methods, ESPRIT and the Toplitz approximation method (TAM), for estimating the direction of arrival (DOA) of plane waves in white noise in the case of linear equispaced sensor array. It is shown that the least-squares versions of ESPRIT and TAM result in the same estimate and are statistically equivalent. It is also shown that, asymptotically, the estimates obtained using least-squares ESPRIT and total-least-squares ESPRIT have the same mean-squared error. Expressions for the asymptotic mean-squared error in the estimates of the DOA are derived for both methods. Simple closed-form expressions are derived for the one- and two-source cases to get further insight. Computer simulation results are provided to substantiate the analysis.>

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
