A standard index of spatial resolution for distributed targets in synthetic aperture radar imagery
2011
International Journal of Remote Sensing
In this paper we outline the need for a consistent method of quoting SAR resolution given the influence of speckle upon SAR images. Standard measures of resolution depend upon the separability of point targets, however this is not a useful analogy in the context of SAR. We contend that quoting resolution for a 3-4 looks product may be unrealistic given the influence of speckle. Our approach considers the separability of targets that differ in intensity by a known contrast ratio, with a ratio of
