A new Phased Array Radar (PAR) system for meteorological application has been developed by Toshiba Corporation and Osaka University under a grant of NICT, and installed in Osaka University, Japan in 2012. The PAR system developed has the unique capability of scanning the whole sky with 100 m and 10 to 30‐second resolution up to 60 km. The system adopts the digital beam forming technique for elevation scanning and mechanically rotates the array antenna in azimuth direction within 10 to 30 seconds. The radar transmits a broad beam of several degrees with 24 antenna elements and receives the back scattered signal with 128 elements digitizing at each element. Then, by digitally forming the beam in the signal processor, the fast scanning is realized. After the installation of the PAR, SIP project has started to develop a new PAR with polarimetric capabilities.

相控阵气象雷达，用于高分辨率的强降水测量

东芝公司和大阪大学在NICT的资助下开发了一种新的气象应用相控阵雷达（PAR）系统，并于2012年安装在日本大阪大学。该PAR系统具有独特的扫描整个天空的能力具有100 m的分辨率和长达60 km的10到30秒的分辨率。该系统采用数字波束形成技术进行高程扫描，并在10到30秒内沿方位角机械旋转阵列天线。雷达使用24个天线元件发射几度的宽波束，并接收128个元件在每个元件处数字化的反向散射信号。然后，通过在信号处理器中以数字方式形成光束，可以实现快速扫描。安装PAR之后，
