Array shape calibration using sources in unknown locations--Part I: Far-field sources

Abstract: This paper deals with source localization using a two-dimensional array of sensors whose locations are not known precisely. If only a single source is observed, uncertainties in sensor location increase errors in source bearing and range by an amount which is independent of signal-to-noise ratio and which can easily dominate overall localization accuracy. Major performance gains could therefore result from successful calibration of array geometry. The paper derives Cramer-Rao bounds on calibration and source l… Show more

The HCRB satisfies the following inequality on the MSE: (1) where is the so-called Hybrid Information Matrix (HIM) defined as [2] (2) where . When the deterministic and the random parts of the parameter vector are assumed to be independent, and after some algebraic manipulations, the HIM can be rewritten as (see [3, eq.…”
