EM based Stochastic maximum likelihood approach for localization of near-field sources in 3-D
Authors:
Publisher and Date:(Walter De Gruyter Gmbh, 2004)The goal of this paper is to estimate the locations of unknown sources in 3-D space from the data collected by a 2-D rectangular array. Various studies employing different estimation methods under near-field and far-field assumptions were presented in the past. In most of the previous studies location estimations of sources at the same plane with the antenna array were carried out by using algorithms having constraints for various situations indeed. In this study location estimations of sources ...

Unconditional maximum likelihood approach for localization of near-field sources in 3-D space
Authors:
Publisher and Date:(IEEE, 2004)Since maximum likelihood (ML) approaches have better resolution performance than the conventional localization methods in the presence of less number and highly correlated source signal samples and low signal to noise ratios we propose unconditional ML (UML) method for estimating azimuth elevation and range parameters of near-field sources in 3-D space in this paper Besides these superiorities stability asymptotic unbiasedness asymptotic minimum variance properties are motivated the application ...
