Precipitation class weather phenomena testing arrangement

The utility model discloses a precipitation class weather phenomena testing arrangement. There is doppler's type precipitation radar through fixed mounting in the railcar, can be used to detect precipitation kinds such as drizzle, rain, snow and whether take place and the starting time and the stopping time. The precipitation radar adopts the doppler frequency shift measuring technique to detect sleet particle drop speed, calculates precipitation intensity, precipitation type and precipitation. The fixed mounting precipitation class weather phenomena appearance that awaits measuring in the railcar, measuring weather phenomena that can be timely can improve the precision of precipitation class weather phenomena test through installation doppler type precipitation radar in the railcar with the precipitation class weather phenomena appearance that awaits measuring. 本实用新型公开种降水类天气现象测试装置。通过在轨道车上固定安装有多普勒型降水雷达，可用于检测毛毛雨、雨、雪等降水种类是否发生及起止时间。降水雷达采用多普勒频移测量技术检测雨雪粒子降落速度，计算降水强度、降水类型和降水量。在轨道车上固定安装有待测降水类天气现象仪，能够及时的检测天气现象，通过在轨道车
