A new tool for experimental investigation of chaos: theory and applications

The paper is devoted to the description of a new method for the experimental research of chaotic processes based on the modern methods of time-frequency analysis with high resolution. The method does not demand power estimations of a spectrum. The method is based on the analysis of form similarity between a signal and clear sinusoid with certain frequency (form-analysis) that leads to the high method's resistant to noise and to trends. In the experiment the substantive theses of the nonlinear theory of determinate chaos have been confirmed. The new effects, which have been not described earlier, have been shown in the theory. Prospects of use of the form-analysis in various spheres of knowledge have been shown.
