Physical Sciences Inc. (PSI) proposes to develop a new general purpose computational code to evaluate the effects of high power microwaves (HPMs) and lasers on materials and entire systems. This Personal Computer Analysis Tool for Directed Energy Weapons (PCAT-DEW) will enable the vulnerability evaluation of specific weapons systems or the lethality of specific DEWs. A key architectural design feature of the new code will be to directly utilize the detailed geometric models that have evolved over the years for detailed conventional and/or nuclear effectiveness evaluations. The leveraging of these resources makes the task of creating PCAT-DEW focus on incorporating the appropriate physical models. The Phase I effort will include the delivery of a preliminary version of PCAT-DEW including laser and HPM models. The complete code will be designed, developed, tested, demonstrated, and documented in Phase II. The key attribute of the validated PCAT-DEW code will be its ability to utilize existing structural models for weapon systems. The operational PCAT-DEW code will have direct applications in government and industry for evaluating either system vulnerability or weapon lethality. The PC-based code can be used to make efficient assessments of material/system behavior due to HPMs and lasers. Computer code sales would be to government agencies and the military aircraft industry. Considerable test and evaluation support is also anticipated using PCAT-DEW.
