Abstract

When images of remote galaxies/stars are observed by radio telescope, much sensitivity can be blurred by interference. This interference can be caused by both the atmosphere and man-made sources. Specifically, the Russian GLONASS satellite system transmits data at a bandwidth wherein much information important to radio astronomers is radiated by astronomical objects. A real-time DSP-based system is needed to adaptively remove the interfering signals and restore clarity to the radio astronomy signal.
