Abstract :
To the problem of pulse signal propagation in a chaotically inhomogeneous media is devoted a great number of papers. The behavior of the running power spectrum (RPS) of pulsed radiation in a weakly dispersive chaotically nonstationary media was investigated at one-dimensional spatial-temporal permittivity fluctuations using the statistical moment method. The investigations of the features of the normalized RPS in absorptive random medium at both one-dimensional spatial-temporal dielectric permittivity and conductivity fluctuations is investigated.
