Abstract
The processing of information signal parameters under conditions of inertialess nonlinear transformation of an input mixture of signals and narrow-band non-Gaussian interference Considered.яThe nonlinear processing of signal parameters is analyzed in the ranges of small and arbitrary detuning between the measured signal parameters and their estimates, as well as at a random signal-to-noise ratio at the gauge input.яTwo variants of optimization of a multichannel discriminator by the criterion of the minimum of the generalized rms error and their corresponding structural schemes were obtained.яThe vector of optimal amplitude characteristics of the nonlinear transformation unit.яIt is shown that the discrimination and fluctuation characteristics of the discriminator are given by the average error signal and its dispersion
