DOP (Degree of Polarization)ΒΆ

This functionality computes the degree of polarization for compact polarimetric SAR data. The required input and the computed output are as follows:

input : input_c2_folder, window_size, tau
output: DOP_CP.bin

The conventional degree of polarization in terms of stokes paramters can be written as follows:

\[\text{DOP}_{cp}=\frac{\sqrt{S^2_1+S^2_2+S^2_3}}{S_0}\]

where,

\[\begin{split}S_0=\text{C11+C22};\qquad{}S_1=\text{C11-C22};\\ S_2=\text{C12+C21};\qquad{}S_3=\pm\text{j(C12-C21)}\end{split}\]
