Abstract
Clarifies the use of interferometry on Radarsat-1 in mid- and long-term intervals between two acquisitions, taking into account changes in the evolution of the azimuth Doppler since April 1999 to maximize coherence and signal to noise ratio. This study is based on fine mode acquisition over Piton de la Fournaise volcano (La Re´union island) and shows examples of displacement fields of the July 1999 eruption.
