Meeting the increased complication of the problem of surfaces remote sensing with the synthesis aperture radar (SAR) use, requiring more high level of resolution and the need in performing of the multiparametric measurements, the necessity of the multichannel SAR construction appears, which could receive signals in the different frequency bands, of different polarization, from different directions etc.

In the proposed paper the algorithms of such a combined processing are examined. These algorithms were synthesized by the solving of the optimization problems. They include the classic operations of the aperture synthesis and operations of the adaptive signal whitening, operations of the Earth covers parameters and statistical characteristic calculation as well.
