Abstract： The possibility of describing the time-dependent processes of scattering by underlying surfaces and the clear sky, as well as the seasonal behaviour of the refractive index of troposphere by using nested semi-Markov processes has been considered. Local Gaussian models can be used to describe the process inside each phase state. The possibility of describing the statistics of reflections from the sea and the refractive index by using Kravchenko finite functions has been shown for the first time.
Key words： semi-Markov processes; Kravchenko functions; atomic functions; scattered signal
