| Abstract | In this paper, the polarization parameters of geomagnetic pulsations recorded during a large geomagnetic storm on March 24, 1991 are calculated using the multiwavelet transform and the Singular Value Decomposition (SVD). Through the first right-singular vector and the singular values, obtained from SVD of the multiwavelet eigenspectral matrix we determined the polarization parameters of the hydromagnetic waves in the time-frequency domain. The results showed that this method is a powerful tool to detect pulsations events mixed to noise with high degree of polarization allowing determinate the polarization parameters continuously in both time and frequency. The fine continuous structure of time-frequency domain of spectral and polarization parameters is suitable to distinguish regular and irregular pulsations that have wide spectral band and short-lived time complex waveforms. The multiwavelets polarization method demonstrated have particular importance to localize polarized pulsations events that is associated to the coherent sources of MHD mode propagation waves in the magnetosphere, mailing during magnetic storms. |
