The M714SDP S-band dual polarization full coherent weather radar is a new generation weather radar 

of China, which is a version with addition of dual polarization function based on the Doppler weather radar. It 

has two operation modes, one is the dual linear polarization transmit/receive mode, the other is the horizontal 

linear transmit and dual linear polarization receive mode.

The M714SDP can detect in real time not only the conventional Doppler weather parameters, such as 

echo intensity (dBz), radial velocity (v) and spectrum width (w), but also the dual polarization Doppler weather 

parameters, such as echo horizontal vertical differential reflectivity factor (ZDR), special differential phase 

(Kdp), zero delay correlation variable phv (0) and linear depolarization ratio (LDR). The radar can detect the 

shape, size, pointing angle and dielectric constant of relevant particles to realize the identification of echo 

characters, improve the accuracy of quantitative measurement on precipitation so as to do more accurate 

weather forecast. The radar is applicable for weather, weather artificial intervention, water conservancy, 

aviation, military and scientific research sectors.
