Abstract

The feasibility of using the High-Power Auroral Simulation (HIPAS) facility for the creation of a linear array of ionospheric Hertzian dipole sources is investigated and presented as a possible ELF/VLF communication system, as well as an ionospheric diagnostic technique. Linear ELF arrays consisting of at least two elements can theoretically be used to monitor, in real time, the ionospheric conditions in the vicinity of the HIPAS facility. This provides a means of studying irregularities due to turbulence or wave structures within the D region. Several experiments have been proposed for far-field confirmation of ELF beam steering within the Earth-ionosphere waveguide, including varying the progressive phase and interelement spacing of an ELF array in a precise temporal sequence. The successful creation of two-element ELF ionospheric arrays using HIPAS is reported.
