Multiple-array passive acoustic source localization in urban environments

Multiple-array passive acoustic source localization in shallow water.

This paper considers concurrent matched-field processing of data from multiple, spatially-separated acoustic arrays with application to towed-source data received on two bottom-moored horizontal line arrays from the SWellEx-96 shallow water experiment. Matched-field processors are derived for multiple arrays and multiple-snapshot data using maximum-likelihood estimates for unknown complex-value...

Robustness of Acoustic Multiple-Source Localization in Adverse Environments

In this paper the robustness of a previously introduced localization algorithm for multiple acoustic sources is investigated and compared to two popular single-source localization algorithms. To show the versatility of the proposed method, experiments are conducted in various environments with different reverberation times and background noises. In addition, moving speakers are used to show the...

Array Processing: Underwater Acoustic Source Localization

near-field source localization in nonhomogeneous environments

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

Localization in Multiple Source Environments: Localizing the Missing Source

Experience in real-world listening situations suggests that listeners, in general, have a great deal of spatial information about multiple concurrent sounds in an auditory scene. Despite this, laboratory data would suggest that listeners should operate quite poorly in such environments. This study employed environmental sounds that would naturally occur in real-world auditory environments and m...
