AbstractCameron's coherent target decomposition (CTD) and classification are discussed in the context of SAR, and the limitations of Cameron's classification are examined. It is shown that Cameron's classification leads to a coarse scattering segmentation because of the large class dispersion that corresponds to a SAR system with about ±5 dB channel imbalance. The application of Cameron's method within known SAR radiometric calibration requirements limits the utility of the classification. A new method, named the symmetric scattering characterization method (SSCM), is introduced to better exploit the information provided by the largest target symmetric scattering component, under coherent conditions. The SSCM, which expressed the symmetric scattering in term of the Poincaré sphere angles, permits a better characterization of target symmetric scattering and the generation of coherent scattering segmentation of much higher resolution, in comparison with Cameron's coarse segmentation.
