The modern battlefield will increasingly make use of energy weapons, and a simulation of their effectiveness and utility on the battlefield will be needed to guide their development and operational implementation. We propose to deliver the first complete validated extensible source-to-propagation-to-target energy transfer computer simulation SEBDEWE ("subdue"), of the effects of radio frequency (RF), acoustic, and laser weapons against personnel and materiel targets, considering weather and other environmental effects, and including original theoretical synergy and supplemental engagement models, and incorporating existing government individual weapon engagement codes. The combined effects of these weapons interacting at the single target level will be treated with eleven original models which will demonstrate the resultant nonlinearly enhanced coupling to the target (synergy). Our software approach is graphical user interface (GUI)-based and object-oriented, and operated standalone on a personal computer. The feasibility of this approach has been successfully demonstrated during Phase I, and both classified and unclassified relational databases, including probabilities of effect and fluences at the target, will be generated at the completion of Phase II, along with lookup tables for separate force-on-force codes incorporating conventional weapons for battlefield-level weapons system evaluation
