Simulation model of ionospheric communication channel

High‐frequency field strength prediction for ionospheric propagation at short‐ and medium‐range radio paths

“…[19] Ionospheric absorption accumulated along the trajectory resulting from solution of the boundary value problem is calculated using generalized theorem of equivalence [Barabashov et al, 2001]. The equivalence relationship between integral absorption values for oblique and vertical propagation in spherical horizontally irregular magneto-active ionosphere is given by…”

“…[3] To account for peculiarities of short-range HF propagation the special method was developed in Rostov state university (Russia) in early eighties of the last century, and since that time it took multiple supplements [Barabashov et al, 2001;Barabashov and Anishin, 2002;Barabashov et al, 2006]. High precision of the method is achieved by using the most reliable and well developed IRI model, proper setting the lower ionosphere, correct accounting for absorption in all ionospheric layers and multihop reflection loss, applying author methods of calculating power and trajectory characteristics of a short wave propagating in magnetoactive spatially nonuniform ionosphere, which differentiates the proposed method from known ones.…”
