Alternative means of satisfying the high bandwidth and protected communications
requirements for New Construction Naval Surface Ships in the midst of conflicting reduced radar
cross section (RCS) requirements were investigated using the systems engineering process.
<p>Various antenna, ranging from parabolic dish antennas to Luneberg lens antennas to phased array
antennas, and feed and amplifier combinations were considered to provide a dual-band Super
High Frequency (SHF) and Extremely High Frequency (EHF) Satellite Communications
(SATCOM) Terminal (SEST).
<p>Through the design of this hypothetical system, the various stages of the systems
engineering process are considered-- definition of need, conceptual design, preliminary system
design, production and installation, and utilization and support. Sample tasks are performed at
each stage in the process (e.g., a system performance specification is prepared in the advanced
system planning stage).
<p>The set of technical solutions that remained in the preliminary design phase are
compared based on life cycle costs. Two approaches are recommended -- one assuming lowest
life cycle cost has highest priority and one assuming that the ability to communicate
simultaneously on SHF and EHF has highest priority. / Master of Science
