| Abstract(in English) | Hazardous weather such as severe storms, tornadoes and hurricanes are small scale weather phenomena. and their detailed profiles are important practically and scientifically. Despite this, conventional radars cannot resolve them, because of their low resolution capability. In this study, we developed a new high resolution Ku-band Doppler radar with scanning capability for meteorological applications. With the new system design, the radar can accurately measure the radar reflectivity factor with the range resolution of 4m and the time resolution of 1min per 1 volume scan (VoS) from the nearest range of 50m to about 15km for 10W power using pulse compression technique. In this paper, details of the system design and signal processing algorithm are described. To demonstrate the accuracy of this system, the radar reflectivity measurements are compared with 2D video disdrometer measurements, and fairly good agreement is shown. In addition, we observed a tornado of F0 scale using this radar and succeeded in detecting the detailed structure. |
