墨脱X波段相控阵雷达数据（2019-2022）

墨脱X波段相控阵天气雷达（X-PAR）由珠海纳睿达科技有限公司研制，采用双发双收的偏振体制，峰值功率为 256 W，采用间隔1.8°（1.5°）方位12层（26层）的 RHI，形成周期为92 s（300 s）的体扫数据，可获取 42 km 范围内的回波强度（ZH）、差分反射率因子（ZDR）、差分传播相移率（KDP）等数据，其距离分辨率为 30 m，阵面预仰角为 15°。该雷达自从2019年7月开始一直在墨脱进行连续观测，除了因电力、网络和通讯等因素引起的观测中断外，雷达数据基本连续。

The Motuo X-band Phased Array Weather Radar (X-PAR) was developed by Zhuhai Narada Technology Co., Ltd. It adopts a dual-transmit and dual-receive polarimetric system, with a peak power of 256 W. The radar performs RHI scans at 12 (26) azimuths with an azimuth interval of 1.8° (1.5°), generating volume scan data with a cycle of 92 s (300 s). It can acquire data including echo intensity (ZH), differential reflectivity factor (ZDR), and specific differential phase shift (KDP) within a 42 km range, with a range resolution of 30 m and a pre-set array face tilt angle of 15°. This radar has been conducting continuous observations in Motuo since July 2019, with nearly continuous radar datasets except for observation interruptions caused by power outages, network failures, and communication issues.
