RAY TRACING INVESTIGATION OF THE MAGNETOIONIC EFFECT ON BEARING DEVIATION IN HF TRANSIONOSPHERIC PROPAGATION.

Abstract

The influence of an earth centered dipole magnetic field upon bearing deviation of medium range hf ray paths in the ionosphere is investigated by using the ESSA three dimensional computer ray tracing program for a variety of conditions involving quasi-parabolic layer models and actual electron density profiles deduced from ionograms gathered during a direction finding experiment. The adequacy of the dipole model is examined by comparing the bearing deviations obtained from it with those for a magnetic field based upon spherical harmonic expansion using Gaussian coefficients.
