SAR INTERFEROMETRY: TOWARDS THE ULTIMATE RANGING ACCURANCY

Radar imaging can be used for applications for which optical imaging cannot, because of its two defining characteristics: amplitude and phase. These applications reveal however that, contrary to what we might expect from its traditional ‘all-weather’ reputation, radar imagery is somewhat affected by cloud cover, which is one of the main limitations in applying the technique we are going to discuss here: radar interferometry [Massonnet, 1997], [Massonnet, 1998].
