BAE SYSTEMS - Analytical Solutions - PEGEM - CT-Analyst For Homeland Defense

CT-Analyst, developed by Naval Research Laboratory (NRL), provides accurate, instantaneous, 3D predictions of chemical, biological and radiological agent transport in urban settings. A model of dynamic urban airflow supplies a 3D database of agent airflow to power CT-Analyst. The accuracy of 3D fluid dynamics simulations with meter-scale resolution is available to the user with zero time delay. CT-Analyst is being incorporated into the PEGEM tool under MDA sponsorship which will allow a user to model a variety of scenarios that encompass both large and small scale events.

CT-Analyst can instantaneously fuse and backtrack sensor readings to two or more separate unknown source locations

PEGEM Provides:

An operational/tactical simulation environment for assessment, planning and training
A tool for parametric studies of chemical, biological and high explosive agent effects
The decision maker a visual indication of hazard areas and potential casualty producing regions
Meso-scale transport and diffusion over minutes to days

CT-Analyst Provides:

Immediate fusion using anecdotal information, qualitative and sensor data to determine unknown source locations
Immediate emergency and consequence assessment
Situation-based escape routes
Emergency management tools include sensor placement optimization
Web broadcast of results

Integrated Tool Provides:

Enhanced modeling capabilities
More complex scenario simulation
Broader range of modeling resolution, from meters to hundreds of kilometers
