source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o

Distributed or decentralized estimation of covariance, and distributed principal component analysis have been introduced studied in the signal processing community recent years, applications array indicated some detail. Inspired by these, this paper provides a detailed development several algorithms for processing. New are proposed DOA methods like root-MUSIC, total least squares-ESPRIT, FOCUSS...

during the last two decades, maximum likelihood estimation (ml) has been used to determine direction of arrival (doa) and signals propagated by the sources, using narrowband array signals. the algorithm fails in the case of wideband signals. as an attempt by the present study to overcome the problem, the array outputs are transformed into narrowband frequency bins, using short time fourier tran...
