Mount Fuji Radar System
The Mount Fuji Radar System is a historic weather radar system located on the summit of Mount Fuji, Japan.
Construction
The installation was completed on August 15, 1964,[1] and is now recorded on the list of IEEE Milestones in electrical engineering. When first built, the Mount Fuji Radar System was the world's highest weather radar (elevation Script error: No such module "convert".), and could observe major weather phenomena, such as destructive typhoons, at a range of more than Script error: No such module "convert".. It was designed by the Japan Meteorological Agency and built by Mitsubishi Electric Corporation.
Technology
The system is notable for its advances in weather radar technology, remote control, and difficulty of construction, as it required the transport and assembly of some 500 tons of material during mountain's short summer. It operated at a frequency of Template:Frequency, with output power of 1500 kilowatts, and a pulse width of 3.5 microseconds. Its antenna was a circular dish, 5 meters in diameter, of parabolic shape, rotating at either 3 or 5 revolutions per minute, and housed within a 9-meter radome.
Use after decommission
The system was decommissioned in 1999, as it was superseded by weather satellites. The dome, radar dish and support equipment were relocated to a purpose-built museum in Fujiyoshida, Yamanashi in 2001. It was replaced by an automated weather system on October 1, 2008.[2]https://www.gov-online.go.jp/eng/publicity/book/hlj/html/201801/201801_09_en.html
