Propagation model for transionospheric fluctuating paths of propagation: Simulator of the transionospheric channel

Abstract

[1] A new model for scintillation on transionospheric links, based on a hybrid method and valid for strong scintillations, has been developed and used to construct a software transionospheric channel simulator. The method is a combination of the complex phase method and the random screen technique. The parameters of the random screen are determined as the result of a rigorous solution to the problem of propagation inside the ionosphere using the extended Rytov approximation (the complex phase method). The random two-dimensional spatial spectrum at the screen is then transferred down to the Earth's surface employing the rigorous relationships of the random screen theory. Thus the complex phase method can adequately introduce a random screen below the ionosphere for L-band frequencies. The technique is capable of producing statistical characteristics and simulating time realizations of the field for a wide range of input parameters. Preliminary results are presented for both weak and strong scintillations.

A global ionosphere scintillation propagation model for equatorial regions

“…The model presented in this paper (Global Ionospheric Scintillation Propagation Model, GISM) uses the Multiple Phase Screen (MPS) technique (Knepp 1983;Béniguel 2002Béniguel , 2004Gherm 2005). The locations of transmitter and receiver are arbitrary.…”

On the Capacity of Mid-latitude High Frequency Ionospheric Channel

“…Subsequently, during propagation, phases and amplitudes of transionospheric electromagnetic waves fluctuate randomly [20,21]. Mid-latitude HF-ionospheric transmission is being one of the interesting solutions for military and strategic communications [4][5][6][7]. The existence of the turbulent ionosphere leads to the amplitude and arrival time fluctuations.…”

Kalman Filter Based PLL Robust Against Ionospheric Scintillation

“…The capabilities of a GSS8000 Spirent signal simulator available at the University of Nottingham have been exploited in conjunction with a physics based scintillation model, the SPLN (St Petersburg, Leeds, Newcastle) [13], in order to recreate a high latitude scintillation scenario. The SPLN model requires as input the ionosphere background profile, in terms of electron density, obtained from the Nequick model [14], geomagnetic and solar activity indices, the spectral index, cross field outer scale and aspect ratios of irregularities, and the carrier frequency of the signal.…”
