Innovative Approaches to Increased Power and Efficiency in Components for X-Band Radar for Ground-based Midcourse Defense (GMD)

Two and Three Dimensional (2D/3D) Miniaturized Dielectric X-band Fractal Noise Filter Research The proposed research will investigate miniaturization of the Fractal Noise Filter (FNF), a low cost, passive Signal to Noise (SNR) enhancement device This device could be integrated into radar transmit-receive (T/R) modules if appropriately designed and sized. Miniaturized FNF devices will be designed and evaluated. SNR enhancements, insertion losses, and critical performance parameters will be investigated for these miniaturized devices, since new materials and structures will be used. Higher loss and unique circuit fabrication processes using high dielectrics will be researched. T/R Module component sized geometries will be pursued for the potential insertion into GMD radar T/R modules. FNF performance parameters for these miniaturized devices will be compiled into a data base including: insertion losses, VSWRs, and phase-amplitude ripple characterizations, etc. These parameters will be recorded in an FNF data base and reflected in the feasibility of the insertion of FNFs into GMD radar T/R Modules
