714SDP型双偏振天气雷达
714XDP
DUAL POLARIZATION WEATHER RADAR
中国新一代X波段双偏振全相参多普勒天气雷达，在多普勒天气雷达的基础上，增加了双偏振功能。具有两种工作模式，即双线偏振发射、双线偏振接收模式和水平线性发射、双线偏振接收模式。
该雷达不仅实时探测回波强度（dBz）、径向速度（v）和谱宽（w）等常规多普勒气象参数，还可实时探测回波水平垂直差分反射率因子（ZDR）、差分传播相移(Kdp)、零延迟相关系数ρhv(0)和线性退偏振比（LDR）等双偏振多普勒气象参数，探测出有关粒子形状、尺寸、指向角和介电常数等参数，实现对回波特性的识别、提高对降水的定量测量的精度，从而进行更准确的气象预报。适用于气象、人工影响天气、水利、航空、军事和科研等部门。
The 714XDP
X-band dual polarization full coherent Doppler 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 714XDP 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 is also available to 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 used for applications in weather, weather artificial
intervention, water conservancy, aviation, military and scientific research
sectors.
