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 metre range of the lengths of the waves. The digital simulation mathematical model radar metre 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 metre range of the lengths of the waves at realization much-frequency and two-frequency of the ways of the recognition for purpose with feature: D=350 km, σц=1м2, v=300 m/c. It is installed that most range of the finding to standard purpose at satisfaction of the requirements on probability, time and range of the recognition, is provided when use two-frequency method. 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 metre range of the lengths of the waves with refer-ence 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.
