HAARP Research Program (High Frequency Active Auroral Research Program) is an American research initiative focused on the ionosphere to develop new radio communication technologies and special military uses. Objectives: Investigating the effects of artificial ionosphere excitation to improve radio wave communication and surveillance. Tools Used: Powerful HF radio transmitter (IRI) with 180 antennas. VHF and UHF radars. Magnetometer and other advanced communication systems. Location and Time: Research station located in Gakona, Alaska. Research started in 1990, with HAARP station established in 1993. Participants and Funding: Funded by the U.S. Air Force and Navy, in collaboration with universities and DARPA. Involves scientists worldwide and many U.S. universities. Experiments and Results: Project transmits at 3.6MW in the HF range (2.8MHz to 10MHz), studying effects on the ionosphere. Experiment objectives include improving communication and navigation in both private and military sectors.
