Fractal Approach of the Ionospheric Channel Scattering Function
نویسندگان
چکیده
The applicability of fractal measurements to the ionospheric scattering function considered as a fractal object has already been demonstrated. Nevertheless in the high resolution method, the chaotic behavior of the object analyzed was deliberately restricted to the two dimensions of propagation delay and Doppler shift. Good results were obtained but we also realized that an important part of the information was missing in the 2-space procedure. A third dimension embodied in the scattering function, seen as a fractal, is the amplitude of the backscattered echo. Considering also the fact that a coordinate in the time-frequency domain can only have one corresponding amplitude, our fractal must be defined as an object of topological dimension 2 embedded in 3-space. With smooth variations, this fractal would be poetically called “a sheet” by some mathematicians.

Measurements and simulation of ionospheric scattering on VHF and UHF radar signals: Channel scattering function
[1] The design and operation of transionospheric VHF and UHF radars requires knowledge of amplitude and phase scintillation due to ionospheric scattering. Phase coherence is of particular importance where long coherent integration periods and large bandwidths are required. A thin phase screen, parabolic equation based, Trans-Ionospheric Radio Propagation Simulator (TIRPS) is described. Modeled ...

متن کاملImproving security of double random phase encoding with chaos theory using fractal images
This study presents a new method based on the combination of cryptography and information hiding methods. Firstly, the image is encoded by the Double Random Phase Encoding (DRPE) technique. The real and imaginary parts of the encoded image are subsequently embedded into an enlarged normalized host image. DRPE demands two random phase mask keys to decode the decrypted image at the destination. T...
