In article are considered statistical distribution bound sign of the recognition three classes integer when processing two- and much-frequency signal, as well as is determined installed of importance required for decision making in decimetre range of the lengths of the waves. The digital simulation mathematical model radar decimetre range was used. Is it for this purpose determined optimum carrying the adjacent frequencies ∆F as two, so and much-frequency of the signal whereupon set of the statistics of the sign of the recognition was realized for each class integer. In the same way in article are brought importances of the factors to efficiency radar decimetre range of the lengths of the waves at realization much-frequency and two-frequency of the ways of the recognition. Use much-frequency signal allows to shorten time for recognition air integer to account of the averaging the sign of the recognition when change the carryinging frequency, however recognition possible only on small quantity integer (1-3 in sector 60 on azimuth) at attitude signal-noise q = 24-28 db. So for recognition of one purposes at attitude signal-noise q ≤ 20 db or need of the simultaneous recognition several integers in sector reasonable use two-frequency way of the recognition. Theoretical value of the work is concluded in determination of efficiency of the using two-frequency and much-frequency of the ways of the recognition in different tactical situation to radar decimetre range of the lengths of the waves with reference to. Validity got result is confirmed by use approved licensed mathematical model. Novelty result mathematical modeling used for reception of the statistical distribution bound sign of the recognition three classes integer when processing two- and much-frequency signal is concluded in need of the production of the decision on using two-frequency or much-frequency of the way of the recognition in different tactical situation. The scientific results of the work can be used for decision of the problem of the recognition aerodynamic integer in existing and perspective radar.
