AURORAL ZONE RADIO STAR SCINTILLATION: MEASUREMENTS AND INTERPRETATIONS,

Abstract

A quantitative evaluation and comparison are made of angular and amplitude scintillation data received at the College, Alaska, experimental station on 68 Mc/s with a lobe-sweep interferometer. The data are reduced with an automatic data processing system. A description is presented of a phase-compensation system which allows readily interpretable measurements to be made which represent the difference between the predicted and apparent position of the radio source. A lead/lag correlation analysis is made between ionospheric absorption, magnetic variation, and the angular and amplitude scintillation data. Some results are presented which show an association between short-term absorption events and the enhancement of scintillation activity. Power spectral analysis and cross-correlation analysis are made of the experimental data. Given several ionization models, the computed ground diffraction patterns are compared with experimental data. A comparison is made between the predicted variation of scintillation depth versus zenith angle, based upon a theoretical model for field-aligned irregularities and some earlier experimental results.
