MP-PAWR
MP-PAWR (MultiParameter-Phased-Array-WetterRadar) is operating in the X-Band mid-range 3D weather radar developed by the Saitama University in Tokyo. The MP-PAWR weather radar is suitable for early warning of extreme weather events like heavy rains and tornadoes. A complete volume scan is completed after one antenna rotation only, i.e. in 30 seconds.
MP-PAWR uses an active electronically scanning phased array antenna with separate antenna groups for transmitting and receiving. The single radiators are dual polarized patch antennas. The lower rectangular elongated antenna array is the transmit antenna. It provides a fixed tuned fan beam pattern. The upper octagonal antenna array contains the receive antennas. With help of the digital beamforming, it generates 10 virtual pencil beams in different elevation angles. The beamwidth in elevation is between 0.5 and 1 degree depending on the off-boresight angle.
The MP-PAWR has been installed at Saitama University since December 2017 and can monitor the entire Tokyo metropolitan area.
