In interests of increase of the relation a signal/hindrance on an exit of the coherent store of the reflected impulses and expansions of a zone of suppression of "blind speeds” at in radar stations it is possible to use high frequency of the repetition which values do not satisfy to a condition of unambiguity of measurement of range. However thus in land radar stations because of presence the big reflexions from local subjects (LS), and also noise emissions on an exit of the jack (card) of LS (CLS) can appear not compensated rests of reflexions from LS not only on real, but also on false ranges. In given article the possible variant of algorithm of work of the digital calculator restoring unambiguity of measurement distance of the purposes is offered.
