Introduction. The substantiation of the methodology for quantitative assessment of the influence of numerical parameters of the probability distribution density of the instantaneous values of the radio interference power and the signal of radio electronic means on the noise immunity of promising radio receivers is given. The application of the technique allows to increase the measurement accuracy and reduce the average probability of reception error due to the instrumental and calculated evaluation of information and informationprobabilistic indicators of electronic protection. The influence of the numerical parameters of the probability distribution density of the instantaneous values of the radio interference power and the signal of radio electronic means on the noise immunity of promising radio receivers is shown. The purpose of this article is the development of methods for quantitative assessment of the influence of numerical parameters of the probability distribution density of instantaneous values of radio interference power and radioelectronic signal signals on information and informationprobabilistic indicators of radioelectronic protection This method allows one to quantify the effect of numerical parameters in the law on the distribution of coefficients and loss data when evaluating the electronic protection performance of the tested radio receivers. Conclusion. The article presents the rationale for quantitative assessment of the influence of numerical parameters of the probability distribution density of instantaneous values of radio interference power and radioelectronic signal on the main information and informationprobability indicators of electronic protection in order to improve measurement accuracy and reduce the average probability of reception error in the interest of improving the robustness of prospective radio receivers. An instrumental and calculating method for determining the suppression coefficient and the derived parameters of the quality of radiofrequency suppression and noise immunity of radioelectronic means, which is the basis of the methodology, has been proposed and tested. Its use has made it possible to reduce the resulting random component of the error in estimating these indicators by 1015, and the average probability of receiving error by 78 in the interests of improving the noise immunity of promising radio receivers. The results of the software implementation of a quantitative assessment of the effect of numerical parameters of the probability distribution density of the instantaneous values of radio interference power and the signal of radioelectronic equipment on the typical information and informationprobabilistic indicators of radioelectronic protection, the probability suppression coefficient and radioelectronic protection indicators derived from it are presented.
