High Frequency Active Auroral Research Program (HAARP)
HAARP was opened in 1990, costing 300 million USD, and was operating under the United States Air Force along with the US Navy, DARPA, and the University of Alaska. The primary purpose of HAARP was to study, analyze and conduct experiments on ionospheric behavior for improving our understanding of the earth's ionosphere as well as enhancing technology for RFRadio Frequency communications.
The primary instrument at the HAARP facility is the Ionospheric Research Instrument (IRI), a high power 180-antenna strong phased array transmitter that can transmit between 2.7 MHzMegaHertz (MHz) 10^6 Hz and 10 Mhz at a maximum effected radiated power (ERP) of 5.1 Gigawatts, or 97.1 dBW. The waveforms found by shortwave listeners from HAARP all came from the IRI.
HAARP uses a variety of waveforms during its operation. One is a sweeping CWContinuous Wave wave that linearly increases or decreases. Another waveform are constant CWContinuous Wave tones that increment up/down at select frequencies from the center carrier. There are still other waveforms including fast pulsing, slow pulses, ionosonde-like sweeps, and combinations of these together at a time.
In addition, HAARP can also operate as a pseudo-radar, transmitting very short pulses or long pulses. At one time it even transmitted Morse code that was intentionally bounced off the Moon for radio hobbyists to hear.
