Edge Detection in SAR (Synthetic Aperture Radar) Imagery Using Gradient Operators,

This memo presents a study of the problems involved in the detection of edge features on high resolution Synthetic Aperture Radar SAR images using gradient operators. An algorithm, proposed recently as a model of the human visual system, which embodied these techniques was investigated and found to give poor performance on SAR images. The reasons for this poor performance were studied and the conclusion drawn that edge detection by gradient operators alone was not appropriate for SAR images.
