Sparsity-driven passive tracking of acoustic sources

  • US Patent No. 9658318
  • Issued: May 23, 2017
  • Status: Active

A system and a method involve acoustic source localization for multiple acoustic sources using passive sonar. Tracks are constructed based on source location maps (SLMs) that reveal the locations of the sources over a grid of tentative source locations. The proposed estimator for the SLMs performs coherent processing of broadband acoustic measurements, capitalizes on the sparse structure of the SLMs, and uses the prior SLM estimate to capture temporal information about the locations of the sources.
