WXR-700X

WXR-700X is operating in X-Band solid-state color weather radar with forward-looking windshear detection.

The flat plate antenna is a phased array antenna that provides a beam 2.5º wide and approximately 2.1º high.

The WXR-700X originally entered service in 1980. The WXR-700X was flight-certified by the FAA for the Boeing 737-300 in 1995. It is e.g. used in Airbus A-300, A-310 and A-320. FMR-200X is the version for military applications as replacement for existing AN/APN-59 and AN/APS-133 radars. It was been installed on the U.S. Air Force’s KC-135’s. There was an attempt to provide a ground based weather radar version WXR-700C-G operating in C-Band.
