摘要: This paper extends the Freeman-Durden decomposition algorithm to compact polarimetric (CP) SAR images under CTLR mode. To solve underdetermined equations for decomposition, contribution of volume scattering is taken as a free parameter, thus giving complete set solutions in an explicit format. The value range then derived, within constraint that weighting factor each component should be nonnegative. feasibility this supported by two data sets from AIRSAR and RADARSAT-2 respectively.
