ABSTRACT
We review experiments in ionospheric modification and long distance propagation performed at the HAARP facility.
Most experiments were in bistatic configuration with the WAVES receiver on the NASA/WIND satellite. Initial
experiments showed scintillation-like variations in low frequency propagation through the earth's ionosphere. A
HAARP-HIPAS transmission experiment set up a spatial interference pattern measured at WIND. The Kodiak
SuperDARN radar scanned the modified region above HAARP and observed the growth of ionospheric irregularities.
Recently, lunar echoes at 8 MHz were detected by WIND. The experiments at HAARP will extend to nonlinear regimes
as power levels increase.
DISCUSSION
Over a period of several years, as the HF Active Auroral Research Program (HAARP) facility near Gakona, Alaska, has
increased total power from 300 kW to 960 kW, we have conducted experiments in ionospheric modification and long
distance propagation. Most of these experiments have been done in collaboration with the WAVES high frequency
