英文摘要	In this paper, based on Lee generalized decomposition model, an adaptive two-component decomposition model is proposed. The PolSAR coherency matrix is represented as the sum of two scattering mechanisms: coherent ground scattering and incoherent volume scattering. The proposed model is under three assumptions: 1) the surface and double scattering are coherent, 2) the surface and double scattering are integrated as the ground scattering, and 3) the average polarimetric orientation angle (POA) of the volume (or Bragg) scattering is zero. The proposed model has three advantages: 1) it can successfully avoid the negative power problem, 2) it is considered without the assumption of reflection symmetry, and 3) the dominant scattering mechanism criterion is not needed in the process of model inversion. The Polarimetric ESAR L-band data of Oberpfaffenhofen were used to show the efficiency of the proposed decomposition model.
