This paper presents an approach for a precise 2D-localization of a mobile station in indoor scenarios by one single base station only. In the approach both, the Direction of Arrival (DoA) and the Time of Arrival (ToA), are estimated using UWB beamformers at both sides of the link. The article describes the algorithm, as well as the required hardware. A duallinear polarized, directive UWB antenn...

In this paper, target localization using bistatic multiple-input multiple-output radar where the source number exceeds the sizes of the transmit and receive arrays, denoted by M and N, respectively, is addressed. We consider the Swerling II target in which the radar cross section varies in different pulses. Two algorithms for joint direction-of-departure (DOD) and directionof-arrival (DOA) esti...

The separation of sources from an array of sensors is addressed in this paper. Based on the Kolmogorov's theorem, an adaptive algorithm is proposed to separate simultaneously all the unknown impinging sources on an aperture of sensors. This method solves the problem of simultaneous DOA (angle of arrival) estimation and source beamforming in narrowband array processing. The Kolmogorov's theorem ...

294 Abstract — In this paper the beamforming and radiation pattern of various linear and planar phased antenna arrays configurations are presented. They are intended for use in indoor location estimation and wireless process monitoring applications based on the determining of direction-of-arrival (DOA) of radio signals by measuring the angle-of-arrival (AOA). Beamforming and the steering of ant...

yy Abstract| A new algorithm is presented for estimating the directions of arrival of signals from an unknown number of moving signal sources. The parameter space is a countable union of cartesian products of the torus, each product space corresponding to a diierent number of signals reaching the sensor array. A Bayesian posterior probability measure is deened on this parameter space by combini...
