Propagation of a Rectangular Chaotic-Phase Radio Pulse in a Cold Plasma Medium

Abstract

Characteristics analysis of the dispersive distortions of a rectangular microsecond chaotic-phase radio pulse modeled using the third-order Chebyshev map of the first kind propagating in a cold plasma medium is performed. Propagation of the pulse away from the radiator is accompanied by the pulse transformation toward a noiselike shape with formation of a “tail”, the length of which can multiply and exceed initial pulse duration. It is established that, in a wide range of parameters describing the randomness degree of the instantaneous phase of the emitted pulse, the medium does not significantly influence subsequent changes in its autocorrelation and frequency correlation functions during propagation.
