Abstract :
Recently, a method called fixed focus shadow enhancement (FFSE) has been developed to sharpen target shadows in synthetic aperture radar (SAR) images. The FFSE method needs to estimate a focus range which is manually selected. However, in a complicated environment, it may be difficult to select the focus range manually. Proposed is an alternative method for the focus range estimation.
