## Abstract

A feature of our problem of restoration of fluctuations in ionosphere height is that the experimental data ψ(t, κ{script}_{k}) obtained at a fixed reception point are functions of time, whereas the function φ{symbol}_{1}(u, y_{2}) to be restored is a function of the coordinates. If we use the assumption that the irregularities migrate transversely, coordinate y_{2} can be "exchanged" for time t. Restoration with respect to the second coordinate u=x_{i}-x_{0}/2 is in effect obtained by using data ψ(t, κ{script}_{k}) on some set of carrier frequencies. The resultant solution of the restoration problem is in the form of an expansion of φ{symbol}_{1}(u, y_{2}) in known functions determined from the observed data ψ(t, κ{script}_{k}). We have evaluated the solution accuracy, which depends on the overall power signal-to-noise ratio at all frequencies used. We have demonstrated that the restoration algorithm contains an optimum number (with respect to accuracy) of coefficients to be evaluated.
