Depolarization occurs when the polarization state changes between the transmitted and received signal. For example, changing a HH to a HV response. There are four mechanisms known to cause depolarization: a quasi-specular reflection as a result of the difference between the Fresnel reflection coefficients for a two-dimensional, smoothly undulating surface [;] a multi-scattering due to target surface roughness [;] a multiple scattering due to volume scattering [;] anisotropic properties of the targets. 3, record 1, English, - depolarization

L'onde polarisée circulairement a le désavantage, lorsque le faisceau radar pénètre la précipitation, de changer son état de polarisation de circulaire à elliptique. Ce changement d'état de polarisation, ou dépolarisation, est attribué aux effets de propagation dus à l'atténuation différentielle et au déphasage différentiel. Les mesures de radar se trouvent contaminées par ces effets et, par conséquent, rendent hasardeuse leur interprétation en termes des caractéristiques de polarisation propres à la précipitation ciblée. 2, record 1, French, - d%C3%A9polarisation
