Figure 5-7. Azimuth viewing effects in Magellan SAR images of an area centered at about 58°S, 200°E in Imdr Regio: (a) obtained in February 1991 with illumination from the west (left) at an incidence angle of about 21 deg; (b) obtained in October 1991 with illumination from the east (right) at an incidence angle of about 24 deg. many bright areas in (a) are not present in (b), which indicates (1) the surface has assymetric roughness with slopes of about 21 deg facing west (to gice the bright return) and much different slopes facing east, or (2) the surface was altered by surficial processes in the 8 months between the two images.
