Abstract

We propose a new sequential deconvolution algorithm, that is applicable to imaging using moving and synthetic aperture arrays. The new method results in a higher resolution and a more accurate estimation than commonly used methods when strong interfering sources are present inside and outside the field of view (terrestrial interference, confusing sources). We demonstrate the algorithm performance over both simulated and real radio astronomical data.
