Processing of HF signals scattered by artificial ionospheric turbulence using fractal analysis

An attempt has been made to apply fractal dimension analysis to HF radio signals scattered from natural and artificially stimulated ionospheric turbulence. Envelopes of the scattered signals in all cases showed a finite fractal dimension as estimated by the correlation integral technique. The signals scattered from artificial turbulence are characterized by a higher correlation dimension, while the statistical characteristics of the signal envelopes of both kind are practically identical. >
