Visualisation and interpretation of PolSAR data based on polarimetric coherence

open access: yesThe Journal of Engineering, 2019
Polarimetric coherence strongly relates to the target scattering characteristics. Coherences of different second-order statistics show different advantages in target discrimination in specific correspondence to physical scattering mechanism.
