Missing radar pulses cause severe artifacts in common synthetic aperture radar images. In this paper, the SAR processor is regularized using the elastic net approach - an additive combination of1- and2-norm - for reducing those artifacts and the noise level. Real data examples show the effectiveness of this approach. © VDE VERLAG GMBH à Berlin à Offenbach.
