We investigate the coherent bremsstrahlung from electrons moving at small angles with respect to a deformed graphene sheet. For an arbitrary periodical deformation of the sheet, a formula is derived for the corresponding cross-section as a function of the radiation direction and frequency. The conditions are specified under which the coherent effects dominate in the total cross-section. In dependence of the parameters of the deformation field and of the angle between the electron momentum and the crystallographic axes of the graphene lattice, the presence of the deformation can either enhance or reduce the bremsstrahlung cross-section.
