Analysis and Synthesis of Model Ionograms Using 3D Ray Tracking Techniques.

Abstract

A system of digital computer programs for use with the Jones-Stephenson ray trace program is described. Using these programs it is possible to: (1) Produce complex ionospheres with simple input techniques; (2) Trace rays through very large ionospheres by the use of disk storage and word packing techniques; (3) Calculate power loss due to absorption, spreading, backscatter, and antenna patterns; (4) Produce leading edge ionograms, a dominant feature of full backscatter ionograms; (5) Produce probable model ionosphere parameters from information obtained from the leading edge ionograms; and (6) Produce many forms of ray trace information displays including various synthesized backscatter ionograms.
