AbstractModern military aircraft carry many microwave and RF systems which must operate in close proximity to one another. Radio frequency interference (RFI) is virtually inevitable. The EA-6B Prowler electronic warfare (EW) aircraft presents a particularly severe interoperability problem because its primary mission is to jam enemy radars. Specifically, the performance of life-critical identification, friend or foe (IFF) systems is degraded by spurious signals and harmonics from on-board jamming systems. Toyon Research Corporation proposes to build on a successful phase I effort to design a shaped-pattern antenna or antennas to combat radio frequency interference to IFF, TACAN, and VHF/UHF communications systems on the EA-6B. We will use our novel anti-jam fixed reception pattern antenna (AJ-FRPA) design techniques to develop an antenna whose pattern is shaped to maximize isolation between the victim antenna and the jamming antenna.
