Full-pol data format#
The package supports full polarimetric SAR data in the following matrix representations:
S2 (Scattering matrix)
C3 / C4 (Covariance matrix)
T3 / T4 (Coherency matrix)
Each format can be provided as .tif or .bin/ .hdr files with associated metadata.
S2 – Scattering Matrix#
Note: All elements of the scattering matrix are in complex data type.

C3 / C4 – Covariance Matrix#
Note: All elements of the covariance matrix are stored as float values. Complex-valued entries are separated into real and imaginary components. C4 includes additional terms compared to C3.
