A Critical Analysis of Decomposition Strategies in Physical Model-Based Decomposition Techniques

Progression towards the different scattering models has fulfilled some of the awaited requirements in the physical model-based scattering power decomposition techniques. Among these, the complete utilization of terrain information has recently been achieved by the development of helix and compounded scattering components. However, the achievement comes up with the expense of some adverse effect on the decomposition result. As occasionally, the power associated with any particular component gets overestimated. Apart from that, an enhancement in the percentage of negative scattering pixels has also been observed as the advancement propagates. Paper briefly concentrated on the analysis of decomposed scattering power and negative scattering pixels on the ALOS PALSAR 2 datasets over the San Francisco Bay Area, CA, USA, when being implemented under the different decomposition strategies.
