Аннотация : The problem of remotely diagnosing a "rough" earth surface and dielectric subsurface structures in the short-wave radio wave band. A new incoherent method for estimating the signal-to-noise parameter is proposed. This range makes it possible to diagnose a subsurface layer of the earth, since the scattering parameter is also determined by inhomogeneities in the dielectric permeability of subsurface structures. By using this method to organize a monitoring program through sounding, it is possible to identify the areas of variation for these media, for example, for hazardous natural phenomena, changes ecosystems. The idea underlying the method for determining this parameter is that, by having synchronous information about a wave reflected from the ionosphere and one reflected from the earth and the ionosphere (or having passed through the ionosphere twice when probing from a satellite), it is possible to extract information about the scattering parameter. A comparative analysis was performed, and it showed that, according to the analytical (relative) accuracy of the definition of this parameter, the new method is an order of magnitude better than the widely used standard method. Evaluation of the analytical errors in estimating this parameter prompt us to recommend the new method instead of the standard one.
