Examples of scattering from small scale density scatters, sound reflecting from a slitted rigid object and sound propagation through a jet are accurately modelled by the proposed methodology.
The correlation between the level of small scale density fluctuations and the solar wind speed was recently found by Asai et al. (1998) from the tomography analysis of interplanetary scintillation measurements.
It is shown that the combination of these two effects can result in sufficiently strong dependence of the fractional level of small scale density fluctuations on the solar wind speed.
At larger moving-average length, the small-scale density irregularities are smoothed out and the R max values gradually increase.
The physical quantities to be retrieved are the vertical distributions of the atmospheric temperature, the electron density, the H2SO4 vapor density, and small-scale density fluctuations.
Scintillations of radio waves are caused by the movement of the ray path across small-scale density structures in the atmosphere.
For this purpose the temporal and spatial variability of the Venus atmosphere will be studied by retrieving the vertical profiles of the temperature, the H2SO4 vapor density, and the intensity of small-scale density fluctuations.
From the observed signal power variation, the sub-cloud H2SO4 vapor densities (Jenkins et al., 1994) and the intensity of small-scale density fluctuation (Woo et al., 1980) are obtained.
Woo et al. (1980) analyzed the time series of the signal power observed during radio occultations and compared their spectra with theoretical scintillation spectra based on a theory of wave propagation through small-scale density structures.
One very interesting aspect of EISCAT_3D's ability to support plasma turbulence experiments arises due to its capability for sub-beam width imaging, which will allow the small-scale density irregularities produced by the heating facility to be imaged for the first time.
