Abstract
To resolve the remote sensing problem of the surfaces by means of use of the synthesis aperture radar (SAR) with high resolution it is necessary to perform the multiparametric measurements. This could be achieved with the help of the multichannel scatterometers that could give the possibility to receive the signals in the different frequency bands, of different polarization, from different directions, etc. In this paper the algorithms of such a combined processing are examined. These algorithsm were synthesized by the solving of the optimization problems. They include the classical operations of the aperture synthesis and operations of the adaptive signal whitening, and statistical characteristic calculation of the Earth covers parameters, as well. Some results of the limits of the measurement errors for the electrophysical parameters such as permittivity, the root-mean-sqaure of the height and the correlation radius of irregularities, etc. within the wide range of reference values were studied.
