Over the last few years an enormous amount of research has been devoted to restore astronomical images, but not much work has been reported on the use of multichannel techniques to restore such images. In this work, we rst brieey summarize the research carried out on image restoration within the Converging Computing Methodologies network and then concentrate on the multichannel image restoratio...

Radio-astronomical observations are increasingly contaminated by interference, and suppression techniques become essential. A powerful candidate for interference mitigation is adaptive spatial filtering. We study the effect of spatial filtering techniques on radio astronomical imaging. Current deconvolution procedures such as CLEAN are shown to be unsuitable to spatially filtered data, and the ...
