Abstract. Systematization of the directions of search of a potential limit of superrayleigh resolution is carried out and a question of existence of such limit at the solution of a problem of resolution detection is answered . It is shown that curve probabilities of full resolution of signals define a resolution limit at the fixed probability of a false alarm and coefficient of correlation of signals. The method of imitating modeling for a large number of algorithms of the digital spectral analysis estimated extent of their approach to a potential limit of superrayleigh resolution.

Keywords superrayleigh resolution, resolution, resolution limit, indicators of quality of resolution of signals, digital spectral analysis.
