“Individual arrays detect. FUSE localizes. The engine combines detections from one or more PARse-equipped arrays and produces target state estimates in Cartesian or UTM coordinates. Multiple targets tracked simultaneously. Narrowband acoustic source frequencies identified. The result is a common operating picture built from distributed acoustic sensors.”

“Acoustic data is only useful if it is processed where it is collected. PARse is Vatn's embedded acoustic signal processing software. It ingests raw digitized acoustic time-series and performs filtering, beamforming, normalization, detection, and angle estimation. The output is a set of detections with signal-to-noise ratio, frequency, bearing, elevation, and associated variances. No operator required. No shore-side processing dependency.”
