High Frequency Active Auroral Research Program - Objectives

Objectives

The HAARP project directs a 3.6 MW signal, in the 2.8–10 MHz region of the HF (high-frequency) band, into the ionosphere. The signal may be pulsed or continuous. Then, effects of the transmission and any recovery period can be examined using associated instrumentation, including VHF and UHF radars, HF receivers, and optical cameras. According to the HAARP team, this will advance the study of basic natural processes that occur in the ionosphere under the natural but much stronger influence of solar interaction, and how the natural ionosphere affects radio signals.

This will enable scientists to develop methods to mitigate these effects to improve the reliability or performance of communication and navigation systems, which would have a wide range of uses, civilian and military, such as an increased accuracy of GPS navigation, and advances in underwater and underground research and applications. This may lead to improved methods for submarine communication, or an ability to remotely sense and map the mineral content of the terrestrial subsurface, and perhaps underground complexes, of regions or countries, among other things. The current facility lacks the range to reach these countries, but the research could be used to develop a mobile platform.

The HAARP program began in 1990. The project is funded by the Office of Naval Research and jointly managed by the ONR and Air Force Research Laboratory, with the principal involvement of the University of Alaska. Many other universities and educational institutions of the United States have been involved in the development of the project and its instruments, namely the University of Alaska Fairbanks, Stanford University, Penn State University (ARL), Boston College, UCLA, Clemson University, Dartmouth College, Cornell University, Johns Hopkins University, University of Maryland, College Park, University of Massachusetts Amherst, MIT, Polytechnic Institute of New York University, and the University of Tulsa. The project's specifications were developed by the universities, which are continuing to play a major role in the design of future research efforts.

According to HAARP's management, the project strives for openness, and all activities are logged and publicly available. Scientists without security clearances, even foreign nationals, are routinely allowed on site. The HAARP facility regularly (once a year on most years according to the HAARP home page) hosts open houses, during which time any civilian may tour the entire facility. In addition, scientific results obtained with HAARP are routinely published in major research journals (such as Geophysical Research Letters, or Journal of Geophysical Research), written both by university scientists (American and foreign) or by U.S. Department of Defense research lab scientists. Each summer, the HAARP holds a summer school for visiting students, including foreign nationals, giving them an opportunity to do research with one of the world's foremost research instruments.
