Simulation Analysis of Distance Error Based on Ionospheric Parameter Correction of Reference Source

By using the shortwave ray tracing technique and the quasi-parabolic ionospheric electron concentration model, this paper simulates and analyzes different ionospheric parameters (different critical frequencies, different bottom heights and different half-thickness) within one hop. Based on the ionospheric parameters of the reference source, the ionospheric propagation parameters of different distances are modified, and the distribution characteristics of ground distance errors with group distances are obtained.
