The interference pattern of coherent diffraction radiation (CDR) from a silt target is measured using the extracted beam of the microtron at Tomsk Polytechnic University. A theoretical interference pattern is calculated based on a model developed earlier for calculating the CDR characteristics in the far and near zones with allowance for the detector-sensitivity function. Comparison of the theoretical and experimental interference patterns makes it possible to obtain information about the longitudinal size of the bunch. The results obtained by the proposed and earlier methods agree well with each other.
