INVESTIGATION OF RADIO AURORA, PROJECT AURORA II
Abstract
Existing experimental evidence is shown to be consistent with the idea that auroral backscatter arises from turbulent fluctuations of electron density as described by a Kolmogoroff spectrum. An inner scale of turbulence of one meter is shown to be consistent with the experimental data. It is further shown that the scatter cross section for frequencies greater than 1000 Mc cannot be accurately predicted. A brief summary of an analysis of auroral backscatter amplitude distribution is presented. Occasionally Rice type amplitude distributions are obtained at 49.7 Mc. These distributions admit of only one explanation - that on occasion, over relatively large regions and for intervals of only a few minutes, the electron density in the auroral ionosphere is in excess of 2 x 10 to the 7th power electrons per cubic centimeter.
