Are SAR images useful in geomorphology?
Geomorphology. SAR images are of value in regional geomorphological studies, owing to the fact that minor details are suppressed on SAR images. However, due to the fact that SAR images provide ‘oblique views’, cartographic application is possible only from ortho-rectified radar images. Relief.
What are the effects of illumination geometry on SAR images?
On an SAR image, the position, orientation and extent of look-direction effects (shadows, layover and foreshortening) depend upon illumination geometry—i.e. relief in the area, altitude of the sensor-craft and look angle and look direction. The same area covered from differently oriented SAR flights appears differently (see Fig. 16.22 later).
What is the role of radar in Sar?
The radar response opens up new avenues for discriminating and mapping Earth materials, as the radar signal provides a ‘new look’ at the ground. SAR images possess a different type of geometric distortion, and therefore due care and expertise are required.
What is polarimetry and SAR tomography?
Polarimetry and SAR tomography are new emerging techniques. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves. The technique of SAR imaging and the various aerial and space-borne SAR sensors have been discussed in the preceding chapter.
