"This application allows converting classical polarimetric matrices to each other.\n"
"For instance, it is possible to get the coherency matrix from the Sinclar one, or the Mueller matrix from the coherency one.\n"
"The filters used in this application never handle matrices, but images where each band is related to their elements.\n"
"As most of the time SAR polarimetry handles symetric/hermitian matrices, only the relevant elements are stored, so that the images representing them have a minimal number of bands.\n"
"As most of the time SAR polarimetry handles symmetric/hermitian matrices, only the relevant elements are stored, so that the images representing them have a minimal number of bands.\n"
"For instance, the coherency matrix size is 3x3 in the monostatic case, and 4x4 in the bistatic case : it will thus be stored in a 6-band or a 10-band complex image (the diagonal and the upper elements of the matrix).\n"
"\n"
"The Sinclair matrix is a special case : it is always represented as 3 or 4 one-band complex images (for mono- or bistatic case).\n"
"In order to determine the architecture, the application first relies on the number of bands of the input image.\n"
"1) Architecture HH_HV_VH_VV is the only one with four bands, there is no possible confusion.\n"
"2) Concerning HH_HV_VV and HH_VH_VV architectures, both correspond to a three channels image. But they are processed in the same way, as the Sinclair matrix is symetric in the monostatic case.\n"
"2) Concerning HH_HV_VV and HH_VH_VV architectures, both correspond to a three channels image. But they are processed in the same way, as the Sinclair matrix is symmetric in the monostatic case.\n"
"3) Finally, the two last architectures (dual polarizations), can't be distinguished only by the number of bands of the input image.\n"
" User must then use the parameters emissionh and emissionv to indicate the architecture of the system : emissionh=1 and emissionv=0 --> HH_HV, emissionh=0 and emissionv=1 --> VH_VV.\n"
"Note : if the architecture is HH_HV, khii and psii are automatically set to 0°/0°; if the architecture is VH_VV, khii and psii are automatically set to 0°/90°.\n"
