Investigation of Plasma Phenomena in the Ionosphere Under Natural Conditions and Under Conditions Artificially Perturbed by HAARP
Abstract
Under this contract, Northwest Research Associates (NWRA) is performing measurements of the ionosphere in order to investigate plasma phenomena in both the natural ionosphere and in the ionosphere perturbed by the High-frequency Active Auroral Research Program (HAARP) high-frequency heater. The research being conducted falls within Hanscom Technical Areas 3(a), "Ionospheric Effects Research and Department of Defense Systems," and 3(b), "Ionospheric Research Technology," of the Broad Agency Announcement VS-O3-Ol released by the Air Force Research Laboratory (AFRL). As a contribution to Technical Area 3(b), we are collaborating with scientists and engineers from AFRL, the Naval Research Laboratory (NRL), and other research organizations in the application of diagnostic instrumentation to HAARP. Among the HAARP instruments that we are applying to ionospheric research are three NWRA ITS1OS coherent radio receiving systems for measuring relative Total Electron Content (TEC) and recording scintillation, and an Ashtech Model Z-FX UPS receiver for measuring absolute TEC. We are posting TEC from these instruments, and phase-scintillation records from the ITS10S receivers, on the HAARP Web site (www.haarp.alaska.edu) for telescience applications and for decision-making during active experiments, and we are also focusing on inverting the TEC data tomographically to produce images of the F layer over Alaska. Research topics under the foregoing objectives are reported in Section 2.
