I am using the PolSARpro to process PolSAR datasets. The covariance matrix [C3] was extracted by the polsarpro, and I want to calculate the intensity of ShhShv* (C12). I am confused with the following two equations:
Intensity_C12 = C12_real * C12_real + C12_imag * C12_imag.
Intensity_C12 = sqrt(C12_real * C12_real + C12_imag * C12_imag).
Would you please help me to figure out this problem?
Thank you very much!
