A -- RESEARCH AND DEVELOPMENT OF WAVEGUIDE FEED NETWORK SOL W71B7J8023M161 DUE 041398 POC Deborah Robertson, Purchasing Agent, (301) 394-1203, Beth Smith, Contracting Officer, (301) 394-3371. Contractor shall complete Phase III research program to finalize the design of a waveguide feed network to meet the HPM performance requirements provided by the Directed Energy and Power Generation Division (DEPGD). Design tradeoffs to exploit the state of the art in antenna technology to reduce the size and weight of such radiating systems are included. The Phase III effort will complete the design of a waveguide feed structure for modular WSA antennas appropriate for both L-Band and S-Band HPM systems. The contractor shall conduct the necessary background research and numerical simulations required to evaluate performance including the effect of the feed network such as input impedence, mutual coupling between array elements, etc. The contractor shall identify the parameters in the waveguide feed network that are critical to HPM performance, size and weight, system integration, reliability and safety. The results will be provided in a final report. This award is intended to be made on a sole source basis to Fractal Dynamics, Silver Spring, MD. The principal investigators at Fractal Dynamics have previously supported ARL and has developed antenna performance algorithms under phase II appropriate for application software available to ARL. The sole source award will take advantage of the preliminary design developed in Phase II, and represents the most efficient and low-risk approach to meeting the stringent HPM antenna performance requirements identified by DEPGD. Responsible sources may submit bid, proposal or quotation by facsimile to Deborah Robertson, (301) 394-1162, which shall be considered by the agency. No telephone requests will be honored.
