Ionospheric modification using dual-frequency S-band beat modulation

We attempt to create accelerated electrons near the F2 peak using S-band transmission of two frequencies separated by a frequency close to the critical ionopsheric frequency, fof2. Theory indicates that the amplitude of the RF frequency difference can be enhanced by small ionospheric irregularities, resulting in a very large, local (near Hmf2), power density input into the F2 region near fof2 producing a population of accelerated electrons. These electrons would, in turn, produce 630 nm airglow and the elements of the theoretical "arificial ionospheric mirror". The ob jective of this experiment is to test that theory using dual-frequency S-band trnamission, ISR diagnostics up the magnetic field line, and airglow diagnostics.
