Abstract

It is demonstrated that the difference in spatial spectra for coherent and incoherent scattering SAR (synthetic aperture radar) data can be used as a mechanism to separate the specular reflection and coherent edge diffraction from the signals due to surface scatterers. A spatial-spectral filter is thus designed to make use of this property and applied to process synthetic as well as measured SAR data. A one-dimensional surface image is constructed from the filtered SAR data with a standard matched filter.<>
