Abstract :
This paper addresses interpretation of off-diagonal terms in the coherency matrix of polarimetric SAR data. The off-diagonal terms, especially the correlations between copolarization and cross-polarization are frequently ignored in many studies. We will show that this misconception will introduce errors, especially when imaging rugged terrain areas
