Radio Frequency Interference Removal through the Application of Spatial Filtering Techniques on the Parkes Multibeam Receiver

Kocz, J.; Briggs, Franklin; Reynolds, J


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]
