A Coherent Wideband Acoustic Source Localization Using a Uniform Circular Array

Abstract: In modern applications such as robotics, autonomous vehicles, and speaker localization, the computational power for sound source localization applications can be limited when other functionalities get more complex. In such application fields, there is a need to maintain high localization accuracy for several sound sources while reducing computational complexity. The array manifold interpolation (AMI) method applied with the Multiple Signal Classification (MUSIC) algorithm enables sound source localization of m… Show more

“…SSL can also be distinguished in terms of the microphone arrays’ arrangement [ 26 ]. Circular arrays [ 38 ] utilize microphones positioned around a circular boundary, facilitating omnidirectional sound source localization while presenting challenges in elevation angle determination. Linear arrays [ 39 ] employ linearly aligned microphones, enabling accurate direction estimation within the horizontal plane.…”

“…Although different microphone geometries have been used in studies, uniform linear (ULA) [13] and uniform circular (UCA) [20] distributed, L-shaped, and spherical microphone arrays are more common. Among these microphone arrays, the L-shaped [21,22] microphone arrays and the circular [3,23], spherical [24][25][26][27], and spatial [23] microphone arrays with a multiple of four co-dispersed microphones in the same plane have co-centered and orthogonal pairs of microphones.…”
