Investigation of distortions of the chirp signals in the neighborhood of critical frequencies of ionospheric plasma
AbstractNumerical experiments are performed to investigate the dispersion distortions of chirp pulses propagating in the ionosphere with taking the three-dimensional non-uniformity, anisotropy, and dispersion of ionosphere in dependence on geophysical conditions into account. Propagation, absorption,and the time delay of ordinary and nonordinary waves are analased.
