Using the formulation of electrodynamics in rotating media, we study the effect of rotation on complex interference and diffraction patterns, as observed in the rotating medium's rest-frame. The interference is generated by a set of electrically small scatterers. To observe the rotation footprint, we use Green's function spectral representation in rotating medium and its efficient approximation. Semi-analytic approximations for the rotation-induced pattern distortion are derived. Numerical efficiency of the approximated Green's function usage vs. that of the full spectral representation are briefly discussed.
