Abstract: | The problem of deep sounding of planet interior using ultra wide band radar with synthesized aperture is considered for the
case when anisotropic fluctuations of the ionosphere plasma density take place. Modeling is performed for a number of values
of the medium and radar characteristic parameters. The degree of influence of mutual orientation of the anisotropy direction
of ionospheric fluctuations and of the spacecraft flight trajectory is estimated. It is demonstrated that widening of radar
pulses is determined by characteristic spatial scale of ionosphere plasma disturbances in the transverse direction relative
to the spacecraft flight trajectory. On the other hand, attenuation of the peak power of the pulses is shown to be determined
basically by the longitudinal scale of disturbance correlations. |
