Editorial: Advances in synthetic aperture radar

This special issue includes papers selected from EUSAR 2004. The publisher suggested including the top 10% of the EUSAR 2004 programme. As we had 280 presented papers including posters we came up with a selection of 26 papers. Because of the large number of pages this special issue has therefore been published in two parts. With EUSAR a unique, worldwide forum for everyone working in the SAR field - scientists, system designers, teachers and users - was established. Each EUSAR conference represents the most recent state-of-the-art in SAR in the world and exhibits perspectives for future activities. The selection of papers included in this double issue reflects these intentions.
