Abstract

Ku-band is used for measuring ocean wind velocities from meteorological satellites. Ku-band is also used for broadcasting DirectTV signals from satellites over the United States. The reflection of these signals are seen as RFI by the meteorological satellites and algorithms for detecting and blanking natural signals affected by RFI have to be developed. This paper presents a new algorithm targeted for detecting these DirectTV signals. The algorithm is implemented in firmware and its performance measured using a bread-board real time RFI processor developed for spaceborne radiometers and the DTU Space Ku-band radiometer POLRAD. It is shown that the new algorithm has a better performance than the traditional cross frequency algorithm for wideband RFI. It is also shown that the traditional cross frequency algorithm has a better performance than the new with respect to narrowband RFI. The new algorithm can thus augment but not substitute the tradition cross frequency algorithm.
