Abstract :
Synthetic aperture radar (SAR) interferometry is employed to obtain topographic information. Owing to noise, interferometric information has to be filtered. The wavelet transform can be employed to filter the interferometric phase, maintaining the spatial resolution, but new signal models have to be studied in this domain for further processing
