A Comparitive Study On The Perfermance Of The InSAR Phase Filtering Approches In The Spatial And The Wavelet Domains
WInPF Lee filter FAMM WMF Wavelet domain Interferogram SAR
2014/4/22
In this paper, we studied and tested different filtering approaches of the SAR interferograms in the spatial and wavelet domains. In the spatial domain, we applied the classic Lee filter and the Weigh...
Nonlinear study of the dynamic behavior of a string-beam coupled system under combined excitation
1:1 internal resonance String-beam Multiple scales Chaotic response Stability
