摘要：

Precision and resolution ability of the frequency-modulated signals time-frequency distributions at the formation of these distributions with the help of pseudo-Wigner processors is investigated. Linear-frequency modulated signals and signals with frequency dependence on time to the higher than the first power are considered. The results of the numerical simulation are presented.
