SAR interferometric phase noise reduction usingwavelet transform
Carlos López-Martínez, Xavier Fabregas Canovas, M. Chandra · Electronics Letters · 2001
The problem of synthetic aperture radar interferometric phase noise reduction is addressed. A new technique based on discrete wavelet transform is presented. This technique guarantees high resolution phase estimation without using phase image segmentation. Areas containing only noise are hardly processed. Tests with synthetic and real interferograms are reported.
