Biological Wide-Area Aerosol Detector (BioWARD)


Capability Description: Standalone sensor in weatherproof enclosure detects thermal objects with consistent appearance/behavior to a bioaerosol plume and determines a threat probability.

  • A physics-based plume model is employed to screen thermal objects of interest
  • Thermal objects are tracked across the field of regard, building up a history of attributes associated with each object.
  • Threat probability is generated on a per-object history basis, based on appearance, motion, dispersion, elevation, size, etc.
  • Threat-like objects are geolocated via triangulation of two sensors, reported to the user, and overlaid on a satellite map.

BioWARD deployed at Dugway Proving Ground

Key Features

  •  Employs commercial uncooled thermal and visible imagers and on-board processor,
  •  Powered via shore-power or optional solar panel +12V, 200Ah battery
  •  Outputs accessible over Ethernet, enabling o Direct viewing of video stream over VNC, o Integration to existing network, or o Use in dedicated network allowing built-in KML server to distribute satellite overlay to an arbitrary number of users.
