Abstract
Способ формирования коррелированных случайных сигналов, включающий формирование во временной области по заданным спектральным плотностям S(f) иS(f)стационарных случайных сигналов x(t), y(t)в форме разложения Райса-Пирсона со случайными на каждой гармонике fфазами Θи Ω, отличающийся тем, что случайные фазы Θодного сигнала x(t)определяется на каждой гармонике fметодом случайной выборки случайной величины, равномерно распределенной в диапазоне [-π,π], а случайные фазы Ωвторого сигнала y(t)определяется на каждой гармонике fкак сумма Ω=Θ+Δφ, случайной величины Θ, равномерно распределенной в диапазоне [-π, π]и случайной величины Δφравномерно распределенной в диапазоне [-φ,φ],границы которого определяются через взаимную спектральную плотность S(f)случайных сигналов x(t)и y(t)из решения уравнения:.A method for generating correlated random signals, including the formation in the time domain of given spectral densities S (f) and S (f) of stationary random signals x (t), y (t) in the form of a Rice-Pearson expansion with phases f and Ω random at each harmonic, characterized in that the random phases of a single signal x (t) are determined at each harmonic f by the method of random sampling of a random variable uniformly distributed in the range [-π, π], and the random phases Ω of the second signal y (t) are determined at each harmonic f as the sum Ω = Θ + Δφ, random Θ uniformly distributed in the range [-π, π] and random variable Δφ uniformly distributed in the range [-φ, φ], whose boundaries are determined through the mutual spectral density S (f) of random signals x (t) and y (t) from solving the equation :.
