Abstract : Development and acquisition of naval communication, data, and radar systems for ships is an almost entirely modular process. For this reason, virtually all existing systems have separate controllers, antennas, and transmitters. However, future systems could use existing planar antennas that operate across a range off frequencies and create a variety of complex waveforms, eliminating the need to develop separate antennas and transmitters. Additionally, frequency use plans are expensive in terms of time and effort to develop and change. The Integrated Topside (In Top) joint Navy industry open architecture study published in2010 described the need for an integrated sensor and communication system that is modular, scalable, and capable of performing multiple functions. Such a system requires a scheduling and frequency deconfliction tool that is capable of representing the current antenna configuration and matches those capabilities with requests for frequency space and time. This thesis describes SPECTRA, an integer linear program that can prioritize and optimize the scheduling of available antennas to deconflict time, frequencies, systems and capabilities. It can be uniquely tailored to any platform including naval warships, aircraft, and ground sites.
