Developments of Scattering Power Decomposition From 3 To 7 Components

Scattering power decomposition has been a hot topic for two decades for the analysis of fully polarimetric SAR data. It has advantages such that 1) easy to interpret the decomposition image, 2) RGB color-coding represents scattering mechanism directly, 3) easy to implement, 4) fast computation time, 5) decomposition powers can be used for further analyses, classification, etc. This paper reviews the development of scattering power decomposition from the original 3-component to recent 6-component schemes, and present a new 7-component decomposition using San Francisco image acquired with ALOS-2 quad. pol. data.
