A phase preserving method for RF interference suppression in P-band synthetic aperture radar interferometric data

Abstract

Addresses the least mean square method for estimation and coherent subtraction of the RF interference in interferometric SAR data applications. The authors also compare the results with a phase preserving notch filter. For this purposes the authors use polarimetric interferometric SAR data from a test site in Solothum/Switzerland collected by the DLR's Experimental SAR (ESAR).
