A non-expectable, stable from shot to shot, intensity distribution in a form of interference pattern have been observed. It is shown that the interference is caused by an emerging of imaginary source in the amplifying plasma, which is phase-matched to radiation of generator. That firstly observed phenomenon is determined as X-ray coherent mirage. To explain the obtained result a new theoretical approach is developed.
