Mount Fuji Radar System

The installation was completed on August 15, 1964,[1] and is now recorded on the list of IEEE Milestones in electrical engineering.

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 2880 MHz, 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.

The dome, radar dish and support equipment were relocated to a purpose-built museum in Fujiyoshida, Yamanashi in 2001.
