摘要：

The analysis of hybrid-polarimetric synthetic aperture radar (hybrid-pol SAR) data can be carried out using two different types of analytical approaches. The first approach is by implementing direct-technique (DT), which directly takes hybrid-pol Stokes parameters as input. The second approach is reconstruction-based-technique (RBT), where the pseudo quad-polarimetric (quad-pol) data is reconstructed from the hybrid-pol measurements. Methods under DT and RBT categories have their own strengths and weaknesses, which are thoroughly investigated in this paper. Also, a comparative analysis of these methods is carried out on the basis of their ability for scattering type discrimination and land-cover classification using synthesized as well as true hybrid-pol data. Moreover, a new entropy (H)-based RBT approach is proposed in this paper which is being compared with the state-of-the-art techniques.
