Application of wideband signals for acoustic localization

Abstract

This paper describes briefly the basic ideas underlying different methods of determining the coordinates of objects by passive acoustic methods (passive acoustic location) for wideband acoustic signals, performs comparative analysis, and introduces a modified algorithm for localization of moving objects using the maximum of ambiguity function in application to passive acoustic localization of different noisy objects under various conditions

“…But also different methods, which in mathematical sense can be considered as approximations of the correct mathematical solution, are also widely used. Among them one of the most popular is the method based on the difference of arrival [3,4,5,6,7,8,9,10,17].…”

“…If only the time difference of arrival of waves at the antennas is used, the possible position of the object is limited by the locus of points, which are equidistant from antennas [6]. This locus is formed by the intersection of hyperboloids of revolution, which are formed by each pair of antennas 978-1-5090-1050-9/16/$31.00 ©2016 IEEE…”
