Inverse problem of flexing by flat electromagnetic wave on certain closed cylindrical surface is considered. Addition given results of scattering field measurements are phase function of reflected signal. Exact stating of such problems is given in this work. For their numerical solution, transition from differential to integral equations is done. Intermediate stage for deciding a general task is recovering impedance distribution, under the fixed a form of the object and given complex – valued scattering field. As a result, linear integro – operator equation, which allows efficient regularization, and numerical solution, is obtained.
