Implements and Techniques for the Analysis of Radio Propagation through the Arctic Ionosphere Using Three-Dimensional Ray Tracing.
Abstract
The report describes work done in three-dimensional ray tracing through the arctic ionosphere. An analytical model of the polar trough was developed using data collected or analyzed by AFCRL-LIB. Improved methods for using measurements of plasma frequency in the ray tracing program were effected. A series of display programs were written for the CDC 6600 using ray paths produced by the ray tracing program. A method for calculating energy density to compare with model calculations was developed. The report includes a case study for the mean polar ionosphere using a transmission of 5 MHz. Results for other frequencies as well as other polar models are included in Appendix L. Computer program documentation for all programs and special subroutines developed under this contract are included in the appendices.
