Neste artigo, examinamos as características polarimétricas e o potencial da decomposição coerente na interferometria polarimétrica de radar de abertura sintética (SAR). A decomposição de espalhamento coerente baseada na otimização de coerência pode separar o centro de fase efetivo de diferentes mecanismos de espalhamento e pode ser usada para gerar o modelo digital de elevação do dossel (DEM). Esta decomposição é aplicada a um modelo de espalhamento estocástico simplificado, como o dossel da floresta. Porém, como as características polarimétricas não são bem compreendidas quando a decomposição é realizada, investigamos suas características e potencial usando entropia alfa-polarimétrica e decomposição de matriz de espalhamento de três componentes. Os resultados mostram que o primeiro e o terceiro componentes correspondem à camada inferior e superior, respectivamente, no caso ideal. Nesta investigação são utilizados dados SIR-C/X-SAR do passe de voo de Tien Shan.

Abstract: In this paper, we examine the polarimetric characteristics and the potential of the coherent decomposition in polarimetric synthetic aperture radar (SAR) interferometry. Coherent scattering decomposition based on the coherence optimization can separate effective phase center of different scattering mechanisms and can be used to generate canopy digital elevation model (DEM). This decomposition is applied to a simplified stochastic scattering model such as forest canopy. However, since the polarimetric characteristics are not well understood when the decomposition is carried out, we investigate its characteristics and potential using polarimetric entropy-alpha and three-component scattering matrix decomposition. The results show that the first and third components correspond to the lower and upper layer, respectively, in ideal case. In this investigation, SIR-C/X-SAR data of the Tien Shan flight-pass are used.
