Impact of the plasma fluctuations in the Martian ionosphere on the performance of the synthetic aperture ground-penetrating radar

The effect of the ionospheric scintillations on the performance of the dekameter wave band synthetic aperture radar (SAR) is considered. The numerical model for computer simulations, based on the multiple phase screen technique and accounting for diffraction, is formulated. The result of numerical simulations of the radar pulses is presented and analyzed. The role of the various features of the ionospheric disturbances and their influence on the radar pulse characteristic parameters is figured out and discussed. Both effects of anisotropy of the correlation function of plasma irregularities and their temporal variations are studied numerically.
