Attenuation Correction of Radar Differential Reflectivity for X-Band Dual Polarization Radar
|
Abstract:
Two channels reflectivity and phase can be acquired by dual polarization radar which can transmithorizontal and vertical polarized electromagnetic waves simultaneously.The physical basis of using polarization radar is that the precipitation particles always exhibit oblate ellipse shape duringfalling.The ratio of major and minor axis of precipitation particle is related with the volume at balance.Differential reflectivity is the measurement of physical essenceof ellipticity of the particle.Unfortunately,diff...
