heal.abstract	An increasing amount of interest has been evolved in VHF/UHF SAR applications. These radars have proven to be a very powerful method for underground and obscured object detection. Emerging civilian and military applications of VHF-UHF radar systems include the detection of targets concealed by foliage and/or camouflage, detection of buried objects, and archeological and geological exploration. However the VHF/UHF portion of the spectrum is heavily used for commercial as well as military purposes. The interference power received from the emitters often exceeds the power of the received radar signal by many dB, thereby limiting the systems sensitivity. Two main approaches for the removal of RF interferences can be found at the literature: coherent estimation and subtraction approaches and incoherent spectral or time domain filter approaches. Only some of these approaches are proven to be phase preserving for interferometric SAR data applications. In this paper we address the Least Mean Square (LMS) method for estimation and coherent subtraction of the RF Interference in interferometric SAR data applications. We also compare the results with a phase preserving Notch Filter. For this purposes we use polarimetric interferometric SAR data from the test site in Solothurn/Switzerland collected by the DLR's Experimental SAR (ESAR).	en
