Since 1995, when the diffraction radiation (DR) from relativistic particles was first observed*, the development of new approaches using the DR for charged particle beam diagnostics is continued. The DR appears when charged particle moves close to the media and the electromagnetic field interacts with it. A rather well-known non-invasive diagnostic method of transversal bunch size is to use a slit target**. In paper*** the optical DR from disphase target was proposed to use for non-invasive diagnostics of high energy electron beam. Disphase target consists of the two rectangular flat plates inclined with respect to each other at an angle compared with 1/g, where g is the Lorentz-factor. Recently the feasibility of the disphase target usage for the 6 MeV electron beam size diagnostics was investigated****. In this report we present the further research of the disphase target beam diagnostics. The simulations of the spectral-angular DR characteristics from this target and it application for diagnostics aim are shown. These calculations confirm an applicability of this technique for micron size beam measurements for the case of g>1000.
