Author Description

Small, commercially available unmanned aerial systems (UAS) are an emergent threat to Navy continental U.S. (CONUS) military facilities. There are many counter unmanned aerial system (C-UAS) tools focused on neutralization, and many sensors in place. A system-of-systems, defense-in-depth approach to C-UAS requires a central system to connect these new and existing systems. The central system uses data fusion and threat evaluation and weapons assignment (TEWA) to properly address threats. This report follows a systems engineering process to develop a software architecture for that central system, beginning with a requirements analysis, a functional baseline, and the resulting module allocation. A series of simulations in ExtendSim derives the performance requirements by examining the overall C-UAS scenario with currently available technology. Through a sensitivity analysis, the simulation shows that effective engagement range (combination of initial target range, detection range and neutralization range) is the dominant factor driving response time. The architecture modeled in Innoslate provides a discrete event simulation for system performance expectations. I. INTRODUCTION * A. BACKGROUND * B. PROBLEM STATEMENT * C. SCOPE * D.
