Radio Frequency Interference Removal through the Application of Spatial Filtering Techniques on the Parkes Multibeam Receiver
This paper addresses the first practical application of spatial filtering techniques to data taken with a multibeam receiver. Spatial filters make use of the relative arrival times of a signal at multiple sensors to identify and separate signals from different directions. The method is a consequence of the Karhunen-Loève theorem and relies on the eigen decomposition of the covariance matrix formed from themultiple signal paths. The effectiveness of the spatial filtering techniques is...[Show more]
