| Summary: | This article discusses the problem of selecting a useful radiation source according to its several weakly expressed parameters. For the implementation of the selection algorithm, as well as the calculation of the probability of finding a useful source, the known methods of selection use the integration of multidimensional probability densities of random variables. Such a calculation requires high computational costs, as well as knowledge of the laws of probability density distribution of random variables used for breeding, which is difficult to implement in practice. In order to simplify multidimensional selection, it is proposed to use a selection method based on a complex criterion. The method of selection according to a complex criterion consists in calculating the functionals of the sources on the basis of their parameters, taking into account the weighted coefficients. Such a functional is essentially an application of the ordinary least squares method to obtain an estimate of the degree of compliance of the objects under consideration with specified conditions. And when using weighted coefficients to calculate the value of a complex criterion, less pronounced parameters of the useful signal make a smaller contribution when making the decision about the detection of a useful signal. This article focuses on analyzing the impact of a set of parameters used for selection according to a complex criterion.
