The Integrated Modeling and Test Environments (IMT) CTA addresses the application of integrated modeling and simulation tools and techniques with live tests and hardware-in-the-loop simulations for the testing and evaluation of DoD weapon components, subsystems, and systems in virtual and composite virtual-real environments. DoD application areas focus on multidisciplinary computational methods and real-time techniques. These areas include digital scene generation, six degrees-of-freedom trajectory simulations, real-time test data analysis and display systems for test control and evaluation, and other modeling and simulation integration tools requisite to high-fidelity engineering and closed-loop engagement models (one-on-one and few-on-few) for the simulation of weapon component subsystems and systems in a virtual operational context.

The Environmental Quality Modeling and Simulation (EQM) CTA supports the investigation of DoD impacts on the environment, and the impacts of this environment upon DoD activities. EQM technical activities involve the high-resolution modeling of hydrodynamics, geophysics, and multi-constituent fate/transport through the coupled atmospheric/land surface/subsurface environment, and their interconnections with numerous biological species and anthropogenic activities. Within DoD, this technology is used for concerns ranging from stewardship and restoration of natural and cultural resources on military installations to evaluation of the impacts of environmental conditions on the DoD mobility operations in the battlespace.

The Electronics, Networking, and Systems/C4I (ENS) CTA focuses on the use of computational science in support of analysis, design, modeling, and simulation of electronics from the most basic fundamental, first-principles physical level to its use for communications, sensing, and information systems engineering. Accordingly, ENS activity ranges from the analysis and design of nano-devices to C4ISR systems-of-systems. This focus ties together nano-electronics, acousto-electronics, microelectro-mechanics, optoelectronics, photonics, circuits, and networks through the exploration of passive/active devices, detectors, emitters, and their physical integration and system deployment in a network-centric warfare environment. ENS methodologies have been developed to explore the nano-scale and below (e.g., electronic structure, charge transport, optical, and photonic interactions), as well as at the analog/digital circuit and communications, sensor and system level (e.g., data links and transport including signal propagation) for performance analysis of information warfare systems-of-systems and large tactical networks.

The Forces Modeling and Simulation (FMS) CTA focuses on the research and development of HPC-based physical, logical, and behavioral models and simulations of battlespace phenomenology in the correlation of forces. These simulations are applied to experimentation, training, operational planning, mission rehearsal, system analysis, and acquisition. The acquisition domain includes research and development, test and evaluation, and production and logistics. The FMS CTA also includes the modeling of C4I systems that impact military decision making in war and operations other than war. For example, FMS simulations model the interrelationships and impact on military operations by phenomena such as: the physics of tactical radio propagation, the logical characteristics of network routing algorithms in a lossy environment, and the behavior of networked combat leaders under conditions of uncertainty. A variety of techniques are employed, including parallel discrete event simulation, evolutionary methods, and agent-based simulations that exploit the power of HPC.

The Signal/Image Processing (SIP) CTA covers the extraction of useful information from sensor outputs in real-time. DoD applications include surveillance, reconnaissance, intelligence, communications, avionics, smart munitions, and electronic warfare. Sensor types include sonar, radar, visible and infrared images, and signal intelligence (SIGINT) and navigation assets. Typical signal processing functions include detecting, tracking classifying, and recognizing targets in the midst of noise and jamming. Image processing functions include the generation of high-resolution low-noise imagery and the compression of imagery for communications and storage. The CTA emphasizes research, evaluation, and test of the latest signal processing concepts directed toward these embedded systems. Usually such processors are aboard deployable military systems and hence require hefty packaging, minimum size, weight, and power. System affordability is expected to improve an order-of-magnitude through the development of scalable codes running on flexible HPC systems. This will enable the traditional expensive military-unique 'black boxes' required to implement high-speed signal/image processing to be replaced by COTS HPC-based equipment.
