EVALUATION OF AURORAL PROPAGATION FACTORS: TRANSMISSION LOSS PHASE. PART I. SYSTEM-LOSS BEHAVIOR AND PREDICTION ON SOME HIGH-FREQUENCY ARCTIC PATHS

Studies of high-frequency transmission loss were made on a propagation path along the auroral zone, across the auroral zone and across part of the Polar Cap and curves of its diurnal behavior were drawn.

Description
Summary:Studies of high-frequency transmission loss were made on a propagation path along the auroral zone, across the auroral zone and across part of the Polar Cap and curves of its diurnal behavior were drawn. Attempts made to obtain correction factors to apply to predictions of transmission loss by standard methods for non-auroral paths gave results for the cases studied but revealed great difficulty of interpretation because of lack of knowledge of moding and insufficiently precise knowledge of such parameters as equivalent reflection height. Studies of transmission loss during disturbances showed a variety of effects. The effect of proton events upon a Polar Cap path were not as conspicuous as might be expected, partially because they occurred at times when auroral disturbances spread over the Cap.
