Massachusetts Institute of Technology/Lincoln Laboratory initiated a major upgrade of the Haystack radar antenna requiring replacement of the elevation structure. The upgrade program was jointly sponsored by the United States Air Force and the Defense Advanced Research Projects Agency.

The Haystack radar antenna is a 120 ft diameter Cassegrain system designed and built in the 1960s. To provide a more stable response for 100+ GHz operational frequency, an upgrade program requiring replacement of the elevation structure was undertaken. The new millimeter-wave radar will uses an innovative transmitter design and signal processing to achieve image resolution that is about ten times better than the predecessor radar.
