| Abstract: | In this paper, two dimensional scaled polyperiodograms are introduced to analyze two dimensional mixed processes and harmonics after undergoing quadratic transformation. Frequencies of the mixed processes and frequencies of harmonics after undergoing quadratic transformation can be extracted successfully by the two dimensional second order scaled polyperiodograms and the third order scaled polyperiodograms, respectively. Theory and algorithm are illustrated by simulation examples. |
