Dual-polarization C-band weather radar algorithms for rain rate estimation and hydrometeor classification in an alpine region [PDF]
Advances in Geosciences, 2009 Abstract. Dual polarization is becoming the standard for new weather radar systems. In contrast to conventional weather radars, where the reflectivity is measured in one polarization plane only, a dual polarization radar provides transmission in either horizontal, vertical, or both polarizations while receiving both the horizontal and vertical channels
