The article is devoted to the development of a methodologies for approximate assessing the probability values execution requirements for accuracy of the coordinates and target recognition of equipment Electronic Support Measure (ESM), included the integral performance indicator. List the benefits of using probabilistic performance indicators. In deriving the probability of meeting the requirements for the accuracy of the target coordinates, it was assumed that the equipment belongs to the ESM multichannel system that forms in the space of a fan of rays and determines the bearing relative values of voltage at the output detectors in adjacent spatial channels. The connection of the required probability the value of the potential accuracy of the bearing emitting targets. For this variant of equipment, expressions to assess the average potential accuracy of the bearing. Shows a plot of the average potential accuracy of the bearing on the signal / noise ratio, and the dependence of the probability of fulfilling the requirements for precision positioning equipment ESM on the values provided by the standard error. Upon receipt of the expression for the probability of fulfilling the requirements for the purposes of pattern recognition analysis took into account the possibility of equipment ESM as untunable and tunable parameters. Expressions densities of the probability distribution of the analyzed parameters that were used in the derivation of the desired formula. To simplify the process of recognition of expressions displayed decomposed into elementary processes of the recognition of the twinning. Obtained plots of the probability of meeting the requirements for the distribution of the level of cognition purpose requirements and capability level hardware ESM. A metodologies can be used when comparing variants of radio engineering systems in analysis and synthesis in tasks requiring speed calculations.
