Development of Advanced Radar Technologies for Missile Defense

The Fractal Noise Filter (FNF) has been demonstrated to filter Linear Frequency Modulated (LFM) waveforms from noise thus increasing the signal-to-noise ratio (SNR). Further research is required to fully understand and develop the FNF device. This device is low cost, completely passive and self-contained. Its underlying principles of operation are based on electromagnetic near field interactions. This proposed research will investigate and construct a near field mapping approach that is consistent with fractal antenna near field patterns. Conventional near field measurement techniques are not capable of field mapping fractal antennas. Unconventional near field mapping and measurements will be researched to provide the critical data for a fractal noise filter design methodology. This effort will provide a mechanism for research and understanding of fractal structures and provide insight into how to design and optimize these structures for particular applications. This research is expected to be the basis for a new category of inexpensive, self-contained, compact SNR enhancement technology.
