An algorithm for calculating the parameters of false alarm level stabilization scheme based on order statistics with the choice of «higher value» or «lower value» when segmenting the sorted array is proposed and investigated. The aim of the work is to derive an analytical expression for the dependence of false alarm probability on algorithm parameters, which determine the numbers of ordinal statistics, at each stage of sorting and entering «higher value» or «lower value» logic circuit. An analysis of obtained dependencies shows that the use of segmentation of a sorted array with two stages of sorting leads to difference in threshold signal-to-noise ratio from 0.6 dB to 1.1 dB compared to the algorithm for stabilizing the level of false alarms based on the use of order statistics without segmenting the sorted array. This provides a gain in the number of computational operations from 6,5 to 22 times when choosing sample size M = 64.
