Abstract :
The LMS adaptive filter has been used successfully to suppress radio frequency interference (RFI) from SAR images. This paper describes a method to efficiently implement this filter by integrating it with the range-Doppler algorithm. A technique to reduce the sidelobes created by the filter is described and illustrated on simulated data and on real P-band data
