Latest Patents

Baxley's latest patents include innovative approaches to acoustic source localization. One of his patents, titled "Sparsity-driven passive tracking of acoustic sources," describes a system and method that involve localizing multiple acoustic sources through passive sonar. This method constructs tracks based on source location maps (SLMs) that reveal the locations of sources over a grid of tentative locations. The proposed estimator for the SLMs performs coherent processing of broadband acoustic measurements, leveraging the sparse structure of the SLMs and utilizing prior estimates to capture temporal information about the sources' locations.

Another significant patent is "Passive tracking of underwater acoustic sources with sparse innovations." This invention also focuses on acoustic source localization using passive sonar, capitalizing on the sparse nature of SLMs. It exploits two types of sparsity: one in the support of the SLMs and another in the innovations across consecutive SLMs. The first type aims to construct SLMs with non-zero entries corresponding to actual source locations, while the second type recognizes that few changes occur in the support of consecutive SLMs. Each SLM is derived as a solution to a regularized least-squares problem, encouraging desired sparse structures through a computationally-efficient proximal gradient algorithm.
