A SAR interferogram was obtained from two JERS-1 SAR data sets around Amundsen Bay, west Enderby Land, received at Syowa Station on November 26, 1996 and January 9, 1997. Fringes were found in the interferogram related to topographic height and surface displacements. However, we could not generate a digital elevation model for the area because we did not succeed in carrying out phase unwrapping to estimate absolute phase. We compared the fringe patterns obtained for Tonaugh Island with the topographic map derived from the aerial photographs. Relative heights in the area of flat topography were estimated from the interferogram; the interferogram's fringes agreed with the contour line shapes on the topographic map.
