From Wikipedia, the free encyclopedia “The High Frequency Active Auroral Research Program (HAARP)" is an ionospheric research program jointly funded by the US Air Force, the US Navy, the University of Alaska and the Defense Advanced Research Projects Agency (DARPA).[1] Its purpose is to analyze the ionosphere and investigate the potential for developing ionospheric enhancement technology for radio communications and surveillance purposes (such as missile detection).[2]
The HAARP program operates a major Arctic facility, known as the HAARP Research Station, on an Air Force owned site near Gakona, Alaska.
The most prominent instrument at the HAARP Station is the Ionospheric Research Instrument (IRI), a high power radio frequency transmitter facility operating in the high frequency (HF) band. The IRI is used to temporarily excite a limited area of the ionosphere. Other instruments, such as a VHF and a UHF radar, a fluxgate magnetometer, a digisonde and an induction magnetometer, are used to study the physical processes that occur in the excited region.
Work on the HAARP Station began in 1993. The current working IRI was completed in 2007, and its prime contractor was BAE Advanced Technologies.[1]
As of 2008, HAARP had incurred around $250 million in tax-funded construction and operating costs.
Another important new diagnostic instrument, an 8 X 8 antenna element imaging riometer, has recently gone into operation at the HAARP Research Station. This instrument monitors the weak galactic background noise at a frequency of 37 MHz using a receiving antenna pattern that permits mapping the ionospheric absorption in 64 overhead patches. This instrument, which was also acquired in conjunction with UAF, is similar to a larger imaging riometer currently in operation at the Poker Flat Research Range near Fairbanks.
A new optical shelter has recently been installed at one of the remote instrument pads at the facility. The new shelter includes a 14 ft. telescope dome with shutter and is rotatable through 360 degrees of azimuth. In addition, a new computer controlled telescope has been added to the existing suite of optical imagers and photometers used during imaging research. Taking advantage of its narrow field of view and sensitive CCD imager, the telescope allows the study and characterization of fine structure in the faint airglow produced under certain conditions of HF transmitter operation.
