  1. OKINAWA Is. 200 km Bist #2 (Ogimi) Bist #1 (Onna) COBRA Radar site (26N 35’, 128E 04’) 35 km COBRA (CRL Okinawa Bistatic Polarimetric Radar) as a Main Sensor of a Possible GPM Super Site in Okinawa Shinsuke Satoh, Hiroshi Hanado, Katsuhiro Nakagawa, Tatsuhiro Adachi, and Toshio Iguchi (Communications Research Laboratory, Tokyo, JAPAN) Main characteristics of the COBRA Six kinds of polar-ization waves (H, V, +45, -45, RC, and LC) can be transmitted pulse by pulse. 1st proc. data: stokes parameters and complex correlations 2nd proc. data:ZHH, ZVH, ZVV,ZHV, ZDR, LDR, ρHV(0), φDP, KDP, VEL, Spectrum-Wid, R(Z), R(KDP) Data format: netCDF Software: NCAR’s TITAN Block diagram of the COBRA Okinawa island is located in the subtropics. There is much rainfall with typhoon, Baiu-front, extratropical cyclone, and so on. Antenna patterns of the COBRA main radar COBRA bistatic dual-Doppler areas An example of the COBRA observation sequence optimized by SROT (Sophisticated Radar Operation Technique). ___________________________________________________________ Corresponding author’s address: Shinsuke Satoh, Communications Research Laboratory, 4-2-1 Nukui-Kitamachi, Koganei, Tokyo 184-8795, Japan.
