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
- Direct viewing of video stream over VNC,
- Integration to existing network, or
- Use in dedicated network allowing built-in KML server to distribute satellite overlay to an arbitrary number of users.
Benefits: The approach provides wide area persistent surveillance using low cost sensors and informed, physics based models.
