FIGURE 5.16RGB color composite of a quad polarimetric RADARSAT-2 image acquired over an area southwest of Bonn, Germany on August 29, 2009, in the Pauli representation RGB = (|s_hh − s_vv|², |s_hv|², |s_hh + s_vv|²).

An equivalent and often preferred representation is in terms of the Pauli decomposition,

$k=\frac{1}{\sqrt{2}}\left(\begin{array}{c}{s}_{hh}+s_{\text{υυ}}\\ s_{hh}-s_{\text{υυ}}\\ 2s_{h\text{υ}}\end{array}\right)=\left(\begin{array}{c}{k}_1\\ k_2\\ k_3\end{array}\right)$
