Bernard Eastlund is most famously associated with HAARP because of some patents he filed for speculative uses of natural gas in Alaska.
This article on Skeptoid decribes the problems with this linkage.

Dr. Eastlund's patent, which has since become popularly known (though inaccurately) as the "HAARP patent", is widely reproduced online, often with much commentary from authors making their own interpretations of how it might be used. Specifically, the patent involves using natural gas to generate electricity to create electromagnetic radiation to excite a tiny section of the ionosphere to about 2 electron volts, thus moving it upward along the lines of the magnetic field. The conspiracy theorists, once again, completely ignore the fact that this can only happen in the ionosphere, and they interpret it as a weather control system or earthquake generating system. Such extrapolations are without any plausible foundation.
A further disconnect in this conspiracy claim is that Dr. Eastlund's patent was for a speculative and unproven device approximately one million times as powerful as HAARP. The patent does not mention HAARP, and none of its drawings remotely resemble anything built at HAARP. For perspective, HAARP's antenna array measures about 1000 feet on a side. A device such as that imagined by Dr. Eastlund would have been 14 miles on a side, with one million antenna elements, compared to HAARP's 180. Furthermore, Dr. Eastlund left APTI to found his own company before the HAARP program began, and was never associated with the program
Eastlund did NOT invent HAARP. HAARP is just an ionospheric heater research facility. Eastlund's own patent describes such ionospheric heating as having gone on well before the 1985 patent:

In recent years, a number of experiments have actually been carried out to modify the ionosphere in some controlled manner to investigate the possibility of a beneficial result. For detailed discussions of these operations see the following papers: (1) Ionospheric Modification Theory; G. Meltz and F. W. Perkins; (2) The Platteville High Power Facility; Carrol et al.; (3) Arecibo Heating Experiments; W. E. Gordon and H. C. Carlson, Jr.; and (4) Ionospheric Heating by Powerful Radio Waves; Meltz et al., all published in Radio Science, Vol. 9, No. 11, November, 1974, at pages 885-888; 889-894; 1041-1047; and 1049-1063, respectively, all of which are incorporated herein by reference. In such experiments, certain regions of the ionosphere are heated to change the electron density and temperature within these regions. This is accomplished by transmitting from earth-based antennae high frequency electromagnetic radiation at a substantial angle to, not parallel to, the ionosphere's magnetic field to heat the ionospheric particles primarily by ohmic heating
His job was to find a use for all that natural gas in Alaska. His solution was to propose building a super large ionosphere heater - far bigger than HAARP, and to speculate on loads of interesting usages (without actually explaining how they would work), in order to make the proposal sound interesting.
