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

Demonstrate Enhanced Signal-to-Noise Ratio Fractal Noise Filters Using Existing MDA X-Band Radar LFM Waveforms The proposed research will investigate the application of the low cost, Fractal Noise Filter (FNF) to GMD radar waveforms and quantify the corresponding Signal to Noise Ratio (SNR) enhancements achieved. The FNF's SNR enhancements, insertion losses, and critical performance parameters will be investigated and compiled into a data base. This data base will serve as the potential design guidance for the insertion of theFNF into GMD radars. This research is will be the basis for the development of a new category of inexpensive, easily integrated, compact signal to noise enhancement technologies. The FNF devices are completely passive and self-contained. They require neither external power source nor additional digital signal processing at the output to achieve enhanced SNR. In addition, the characterization of the FNF devices will include measurements of: insertion loss, VSWR, and phase-amplitude ripple. These characterization parameters will also be recorded in the data base and be reflected in the feasibility of the insertion of a Fractal Noise Filter into GMD radar systems.
