Abstract. A method of imaging formation with sub-diffraction angular resolution using a scanning one – aperture terahertz telescope was offered. We describe briefly the scheme of the telescope and the proposed algorithm  for the procedure of scanning and reconstruction of images. The simplest problem of simulation of imaging formation with sub- diffraction resolution on one-dimensional experimental model of scanning one – aperture terahertz telescope has been put in the article. The estimation of  the possibility of improvement of angular resolution up to ~ 140 times was the result of the simulation. Tasks which should be solved in the way of creating a one–aperture two-dimensional telescope with imaging formation with sub- diffraction resolution have been a prescheduled.

Keywords: radio astronomy of terahertz range, space and ground telescopes, methods of improvement of telescopes characteristics, angular resolution improvement.
