Figure 5-3. Geometric distortions in radar images: (a) radar image foreshortening, where the slope facing the radar is compressed to segment A'- B' while the backslope is extended to segment B'- C'; (b) radar layover, an extreme case of foreshortening, where the top of the mountain, B', is imaged before the bottom, A'; (c) radar shadowing, where the backslope of the mountain, B'- D', is not illuminated by the radar, and no data are acquired.
