Abstract :
Cross-entropy for measuring the difference between two scatterers in the polarimetric radar discrimination problem is introduced. Two cross-entropy measures in favour of one scatterer over another are obtained for two independent probability mass functions that indicate the average scattering mechanism and the scattering randomness
