Enhanced Electromagnetic Effects-

In modern Department of Defense (DOD) and Missile Defense Agency (MDA) Radar and Communications Systems, it has been shown that two of the most costly requirements are the effective radiated power (ERP) and target Signal to Noise Ratio (SNR). For MDA radar systems estimates of up to $50M per added dB of SNR have been reported. In its Phase I effort entitled "Influence of Fractal Signals on the Effects of Chaotic States in Electromagnetic Components," GRA designed and developed a passive Fractal Noise Filter (FNF). This Fractal Noise Filter can be added to the receiver side of radar or communication antennas with very little modification and will enhance the SNR significantly. The GRA Fractal Noise Filter: 1) is a purely passive device; 2) has almost unlimited power handling capability and an instant turn-on time; and 3) does not require either additional power or software processing algorithms to operate and to increase the SNR. GRA measurements of the FNF capabilities and demonstrations performed for GMD radar engineers have shown SNR enhancements of up to 15 dB. GRA is proposing a multi-option, Phase II Program that will: 1) Optimize and Test a FNF for existing MDA LFM radar waveforms (Basic); 2) Perform Experimental and Theoretical Studies to Establish the Electro-magnetic principles, underlying the FNF's operation (Option I); 3) Develop and Fabricate an X-band FNF applicable to existing MDA GMD and TMD Radar Systems (Option II); and 4) Miniaturize the FNF using novel advanced 2D/3D configuration technology ( Option III).
