Recurrent analysis of Solar radio bursts

Abstract

In this work it is offered a new method for analysis of time series based on the fundamental property of dissipative dynamical systems – recurrence (repeatability conditions). The aim is to describe dynamic behavior of solar radio bursts by the method of recurrent diagrams. Recurrent diagrams are a graphical instrument which detect a number of basic structures responsible for one or other character of a system development. It is shown that different types of radio bursts have various features in structures. So bursts of type I are characterized by drift topology, showing heterogeneity of a process and a slow change of parameters. For radio bursts of type II a structure of recurrent diagram on topology is contrast, this indicates about a sharp change of a process dynamics, about it’s non stationarity. The received results are well coordinated with physical theory of radio bursts.
