The Doppler-polarization weather radar have many kinds of types in its development.They are divided circular polarization,elliptical polarization and dual-linear polarization according to there shape of transmitting electric wave and are divided x-band,c-band,s-band as well as mm-band according wavelength.This paper introduce one kind of simultaneous horizontal and vertical channel transmission technology that is used in our new development radar.It is a actual multi-parameters weather radar and could obtain the informations about ZH,V,W,ZDR,ΦDP,KDP and ρHV of cloud and precipitation at same time.These information are useful for the research of cloud and precipitation physics as well as weather modification.It will be useful for the development and application of polarization radar in our country.
