Improved four‐component based polarimetric synthetic aperture radar image decomposition

Scattering mechanism ambiguity, negative power problem, and complete utilisation of coherency matrix elements have been the major challenges of the model-based decomposition methods. In this study, the aforementioned issues are addressed simultaneously with an improved four-component decomposition method. In the proposed method, helix scattering power is obtained conventionally, while helix angle compensation is used parallelly for the pixels...
