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.
- 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.

Benefit to Warfighter
The approach provides wide area persistent surveillance using low cost sensors and informed, physics based models.
