| Zusammenfassung |
| In this paper we introduce the field line resonance detector (FLRD), a wave
telescope technique which has been specially adapted to estimate the spectral
energy density of field line resonance (FLR) phase structures in a superposed
wave field. The field line resonance detector is able to detect and correctly
characterize several superposed FLR structures of a wave field and therefore
constitutes a new and powerful tool in ULF pulsation studies. In our work we
derive the technique from the classical wave telescope beamformer and present
a statistical analysis of one year of ground based magnetometer data from the
Canadian magnetometer network CANOPUS, now known as CARISMA. The statistical
analysis shows that the FLRD is capable of detecting and characterizing
superposed or hidden FLR structures in most of the detected ULF pulsation
events; the one year statistical database is therefore extraordinarily
comprehensive. The results of this analysis confirm the results of previous
FLR characterizations and furthermore allow a detailed generalized dispersion
analysis of FLRs. |
