Environment estimation is a challenging task in reverberant settings such as the underwater and indoor acoustic domains. The locations of reflective boundaries, for example, can be estimated using acoustic echoes and leveraged for subsequent, more accurate localization and mapping. Current boundary estimation methods are constrained to high signal-to-noise ratios or are customized to specific environments.

Article Synopsis
  • The text discusses the challenges of passive localization and tracking of a mobile sound emitter in a complex and unknown 3D acoustic environment, particularly when obstacles may block direct lines of sight.
  • It introduces a multistage global optimization architecture that combines various algorithms, including particle swarm optimization and a 3D boundary localization technique, to estimate both the emitter's position and the reflective surfaces in the environment.
  • The effectiveness of this comprehensive approach is tested in a controlled shallow-water environment, showing its potential applicability across different scenarios and improving upon existing methods that ignore the motion of the emitter.
