This paper deals with the characterization of permanent scatterers in polarimetric synthetic aperture radar (SAR) images ofurban environment. Along this line, a scattering property based generalized likelihood ratio (GLRT) test for detection of permanent single and double scatterers, called scat-sup GLRT, is proposed. The method uses polarimetric information within the test, which allows further improvement in detection performance and identification of backscattering mechanisms of the permanent scatterers (PSs). Hence allowing identification and classification of PSs. The proposed framework is evaluated using satellite polarimetric multi-baseline data sets and compared with existing PS detection using SAR tomography framework.
