Annotation:  The dynamic theory of coherent X-ray radiation generated by relativistic electron beam in a single crystal plate has been developed for condition of multiple scattering of electrons. The radiation cross-section averaging was carried out over the rectilinear trajectories of expended electron beam. The expressions for spectralangular characteristic of PXR and DTR were derived for conditions of electron multiple scattering. The numerical calculations of PXR and DTR spectral-angular characteristics were carried out for concrete conditions
