Remote sensing of scattering surface if phase information in registered data is distorted or absent

Radar remote sensing of the sea and land surfaces is considered. Analysis of reflected waves makes it possible to derive information about electro-physical properties and geometric parameters of the surfaces under examination. A new wide practically important class of surface models is described. It is shown that if a profile of a surface relief or its complex scattering function can be approximated by a polynomial then the phase of the scattered field can be uniquely reconstructed upon registered the field magnitude, i.e. the phase problem in the one dimensional case can be successfully solved. Accordingly, a new approach to measured data processing is proposed. Only field intensity is registered and then the phase is recovered. An inverse problem is resolved by means of of well known methods.<>
