Frequency Selective Filter/Switch

The project examines the concept of frequency selective antenna management and supplemental transmit antennas on tactical aircraft which allow continuous jamming and support maneuvering. The project examines tactics and coordinated techniques responding to crew actions and cueing techniques to prompt optimized maneuver synchronization. Phase 1 identifies the threats, the techniques, and estimates performance. The project examines the F/A-18C/D for EW antenna improvement. Phase 1 develops a 3-dimensional EW protection envelope for tactical aircraft responsive to altitude, attitude and maneuvers which produces improved survivability based on the situation. The project defines and evaluates alternative antenna locations, switch and filter concepts, and estimates performance and realizability. The Phase 1 Option addresses alternate switch implementation technologies. Phase 2 develops a prototype managed transmit antenna concept for the F/A-18C/D.
