WR-73
WR-73 was an operating in C-Band weather radar developed by MIT and built by EEC in the early 1970s. With its relatively small antenna with a diameter of 8 feet (about 2.4 m), it was especially suitable for field tests.
Originally it was a conventional, non-Doppler radar because of the simple magnetron transmitter. A modernization to coherent-on-receive radar and thus possible measurement of Doppler frequencies was made in 1986.
It was decommissioned in the early 90s.
