N2 - The coherent diffraction radiation (DR) and Cherenkov radiation (ChR) emitted by bunched electron beam of 6.1 MeV passing near a flat dielectric target have been observed in the millimeter wavelength range. The simple geometry of experiment allows testing different theoretical approaches, which consider the process of simultaneous emission of DR and ChR from dielectric targets. Properties of the radiation have been experimentally investigated in far-field zone. The angular distribution of the observed radiation at various tilt angles of the target in respect to the electron beam have shown the effect of interference between DR and ChR. The comparison of experimental results with the theoretical calculations based on the approach of polarization currents has been done.
