Improved WSBI Inversion for Rothr

Abstract

Wide sweep backscatter ionograms (WSBI) and quasi vertical incidence (QVI) ionograms are routinely collected at over the horizon radar (OTHR) installations operated by the U.S. Navy. The WSBI provides information about ionospheric regions that are far down range from the sounder. In this project a method for the quantitative extraction of this information by means of a leading edge inversion technique is described and applied to data acquired by the WSBI sounder operating at the Chesapeake VA OTHR facility. Because this sounder is used to sample 8 azimuthal sections, maps of plasma frequency at a constant altitude can be derived over a geographic region that covers a 64-80 degree angular sector out to distances of more than 2000 km. In this report we illustrate the unique capability of the OTHR WSBI sounders to provide real time monitoring of the ionosphere over a large geographical area.
