Within the limits of the theory of statistical radio engineering the method of maximum probable estimation of an amount frequency - indivisible radio-waves of radiants of a radio emission are develop. The method assumed shaping of a matrix of mutual energies and an evaluation of global maximas the direction finding of relief for each of distinguish statistical hypotheses. Solv statisticians of a method was invariant to a priori unknown quantity of intensity of noise. The solution about an amount of radio-waves started by results of comparison of solv statisticians with a threshold cho according to criterion of Neumann Pearson and ensur constant demand probability of an error of first kind.

The receiv expressions was fair on a case arbitrary matrixes of coefficients of correlation of noise, configurations of antenna system of an detection-direction finder and performances of a directedness was more its than antenna elements. The offer method are efficient in a case partially and completely the coherent radio-waves accept from radiants of a radio emission.

Use of the method of an estimation in subsystems of radio-electronic investigation of modern complexes of radio-electronic struggle will allow to raise indicators of effectiveness of conducting radio-electronic investigation in the conditions of multiradial distribution of radio-waves.
