THE SYNTHESIS OF OBLIQUE IONOGRAMS BY DIGITAL COMPUTER

Abstract

Oblique ionograms--records of sweep-frequency ionospheric sounders with transmitter-receiver separation of hundreds or thousands of kilometers-- differ from vertical-incidence ionograms in that they cannot be inverted to give ionospheric electron density without making unrealistically drastic assumptions concerning the nature of the ionosphere. Oblique ionograms, however, can be calculated from a known ionosphere. This report describes a method for performing the calculation using a digital computer. The technique takes full account of earth and ionosphere curvatures and allows arbitrary choice of electron density with height and longitudinal distance but not with lateral distance. The geomagnetic field is neglected in the interest of economy, but it could be included.
