The purpose of article is the analytical assessment of probability of resolution of group radar object in the compensation way.
The carried-out analysis of histograms of values of the module of the remains of a compensation way allowed to make a hypothesis that at supervision of single object, the remains are distributed under the normal law of distribution truncated at the left, and at supervision of two objects – in normal way. Check of a consent of the made hypotheses demands knowledge of parameters of laws of distribution, dispersion is basic of which. The method of consecutive functional transformations of a random variable received analytical expression for dispersion of the remains of a signal after its processing by compensation way. After substitution of the analytical description of dispersion in theoretical laws of distribution, according to Kolmogorov\'s criterion, it is established that there are no bases to reject the made hypotheses. It allowed to define analytically value of a threshold and probability of permission of group radar object in the compensation way for one sounding according to noise dispersion at the release of the scheme of the coordinated processing of the detector and to the set level of false alarms.
