Iterative Volumetric Reduction (IVR) Steered Response Power Method for Acoustic Source Localization

Abstract: Background: Steered Response Power–Phase Transform (SRP-PHAT) approach is a breakthrough in the field of source localization in a high reverberant environment, but the substantial computational cost limits its usage in the practical implementation. Objective: This paper presents an efficient SRP-PHAT based, Iterative Volumetric Reduction (IVR) Steered Response Power method for acoustic source localization in non-ideal surroundings. Methods: Developing the coarse acoustic maps in the preliminary iteration… Show more

“…Particularly, WASN-based sound source localization has captured researchers’ attention in the last two decades [ 1 , 2 , 3 , 4 , 5 ]. The existing methods available for passive source localization in WASNs include (1) the received energy-based approaches [ 6 , 7 , 8 , 9 ]; (2) the direction of arrival (DOA)-based approaches [ 10 , 11 ]; (3) the time of arrival (TOA)-based approaches [ 12 ]; (4) the time difference of arrival (TDOA)-based approaches [ 13 , 14 , 15 ] and (5) the steered response power (SRP)-based approaches [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”
