Tool to Predict High-Power Electromagnetic Effects on Mobile Targets

ABSTRACT: The focus of this research will be on developing a model and associated computational tool called HPEM-Expert that is consistent with the Directed RF Energy Assessment Model 2, (DREAM2), which describes and predicts the effects of a high-power electromagnetic (HPEM) signal on a mobile target, to improve on the existing DREAM tool. Our approach will be to develop a modeling and simulation (M&S) based capability that is compatible with and enhances the DREAM framework and methodology. A proven toolkit framework design will be used that employs an innovative fault-tree based Sneak Circuit Analysis (SCA) approach to demonstrate the feasibility of the proposed concept to successfully function in a relevant scenario provided by the government. This framework will combine computational electromagnetics (CEM) solvers with a circuit solver and an SCA module to provide a solid foundation for establishing accurate front-door and back-door coupling models. This will set the stage for Phase II during which we will refine the framework and develop and demonstrate the failure analysis process as well as validate the new capability through detailed component testing and simulation. The initial product to be developed and demonstrated in Phase I will lead to a mature capability that will increase the Air Forces ability to protect its own electronic systems from HPEM effects, as well as to determine the level of damage incurred by/to potential adversaries.; BENEFIT: The product of this STTR project will increase the Air Forces ability to protect its own electronic systems from HPEM events. The commercial sector can also similarly benefit from the technology. For example, the EMI problems encountered on military aircraft are also a serious problem for the commercial airline industry. Commercial aircraft manufacturers currently use relatively crude codes (e.g., spreadsheets) or "back of the envelope" calculations to study EMI and safety problems associated with incident fields from ground radars and other high power sources. Such a sophisticated tool will allow for much greater accuracy and efficiency, which will in turn provide significant time and cost savings as well as enhance safety. Optimizing the design, performance, and application of HPEM-Expert can ultimately help to promote company competitiveness and productivity in these market niches. Also, as a result of the universal need for wireless communication and information collection, there is an increasing need for robust and hardened complex information systems to be integrated on host platforms.
