Abstract
Optically Processed Beam Forming Networks (OPBFNs) have been identified as an emerging technology for phased array antenna applications requiring rapidly reconfigurable multiple beams. OPBFNs have the potential for a considerable decrease in weight and volume over typical phased array antenna architectures. The potential compactness and flexibility of OPBFNs has made them an attractive candidate for an antenna role in the Mars Environmental Survey (MESUR) project. The NASA Lewis Research Center (LeRC) and the Jet Propulsion Laboratory (JPL) are jointly investigating the use of OPBFNs in this application. As its part in this joint effort, LeRC is developing an OPBFN testbed to evaluate OPBFN architectures and components, as well as developing system modeling programs to simulate OPBFN performance. JPL's role in the project is to develop a photonic transceiver that feeds the OPBFN. This paper discusses the modeling and development of the OPBFN testbed at LeRC.
