Abstract:
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 of l1- and l2-norm – for reducing those artifacts and the noise level. Real data examples show the effectiveness of this approach.
