Automatic analysis of diurnal digital ionograms
Abstract
This paper describes the numerical methods used to obtain automatically the main characteristics of diurnal ionograms. The program is used to obtain a representation of a filtered ionogram on computer printout and to tabulate the characteristic parameters such as the critical frequencies, the significant virtual heights, and the maximum usable frequency at a distance of 3000 km.
