Antenna array Cramér-Rao bound design by element relocation
2009 Edition, August 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We consider the use of an arbitrary planar array for direction-of-arrival (DOA) estimation, with the commonly used Cramér-Rao Bound (CRB) as a performance measure. By taking advantage of the cosine structure of the array Fisher information matrix (FIM), the FIM...

Cramér-Rao bound for DOA estimation with antenna arrays and UWB-OFDM signals for PAN applications
2008 Edition, September 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper deals with the computation of the Cramer-Rao lower bound (CRB) for direction of arrival (DOA) estimation of ultra wideband-orthogonal frequency division multiplexing (UWB-OFDM) signals detected by antenna arrays for millimetre-wave applications....

Cramér-Rao Lower Bound on AoA Estimation Using an RF Lens-embedded Antenna Array
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this letter, we investigate the Cramer-Rao lower bound (CRLB) on angle of arrival (AoA) estimation of an RF lens-embedded antenna array. We first derive an expression for the received signal, in terms of intrinsic lens characteristics, using an RF lens-embedded...

Estimation of the Cramer-Rao Bound for Radio Direction-Finding on the Azimuth and Elevation of the Cylindical Antenna Arrays
2018 Edition, July 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper the problem of direction-of-arrival (DOA) estimation for conformal antenna arrays consisting of directive emitters for the azimuth and elevation cases is studied. The expression for the Cramer-Rao lower bound of the DOA estimates variance depending...

Derivation of monopulse angle accuracy for phased array radar to achieve Cramer-Rao lower bound
2012 Edition, March 1, 2012 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Derivation of monopulse angle accuracy for phased array radar to achieve Cramer-Rao lower bound is presented in this paper. Antenna element positions originating from antenna center are used for difference beam taper in this monopulse angle...

Directive antenna arrays for 3D source localization
2003 Edition, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Circular antenna arrays are widely used in positioning systems. Due to their geometry, they are able to provide an equal localization accuracy regardless of the target location. We address those applications for which this is not required. By choosing alternative arrays,...

Methods and Bounds for Antenna Array Coupling Matrix Estimation
2007 Edition, Volume 2, April 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel method is proposed for estimation of the mutual coupling matrix of an antenna array. The method extends previous work by incorporating an unknown phase center and the element factor (antenna radiation pattern) in the model, and treating these as nuisance...

Virtual multi-antenna array for estimating the direction of a transmitter: system, bounds and experimental results
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A method is proposed to estimate the direction of a radio-frequency (RF) transmitter with a mobile, single-antenna receiver. By considering the received signal at several points along its trajectory, the receiver implicitly creates a virtual multi-antenna array, which...

Biologically inspired coupled antenna array for direction of arrival estimation
2010 Edition, November 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We propose to design a small-size antenna array having high direction of arrival (DOA) estimation performance, inspired by the Ormia ochracea's coupled ears. The female Ormia is able to locate male crickets' call accurately, for reproduction purposes, despite the small...

Direction-of-Arrival Estimation in Conformal Microstrip Patch Array Antenna
2018 Edition, Volume 66, January 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The direction-of-arrival (DOA) estimation of a conformal antenna array with directive elements is studied in this communication. The two-dimension Cramer-Rao lower bound (CRLB) is derived for a conformal antenna array by using the active...
