|
|
|
|
All the decompositions implemented are intended for the mono-static case (transmitter and receiver are co-located).
|
|
There are two kinds of decomposition : coherent ones and incoherent ones.
|
|
In the coherent case, only the Pauli decomposition is available.
|
|
In the incoherent case, there the decompositions available : Huynen, Barnes, and H-alpha-A.
|
|
User must provide three one-band complex images HH, HV or VH, and VV (mono-static case <=> HV = VH).
|
|
Incoherent decompositions consist in averaging 3x3 complex coherency/covariance matrices; the user must provide the size of the averaging window, thanks to the parameter inco.kernelsize.
