To date InSAR obvservations of ice flow have used pairs or triplets of observations from both ascending and descending satellite orbits. Employing the surface parallel flow assumption together with a digital elevation model (DEM) has been the only means to derive three dimensional ice flow. We present a new method of deriving 3-D flow from InSAR observations alone, by using data from multiple crossing orbits acquired over Antarctica using Radarsat. We present the technique and compare our three dimensional results to conventional ascending/descending surface parallel flow assumption results, particularly in regard to vertical ice motion.
