The shore-ship communication is an important means of communication between ship formation and land-based command poststhus it is crucial to keep communication smooth.To solve the problem that the random variation of ionosphere affects the simulation of smooth communication zonewe took the one-hop reflection with the highest frequency of wartime communication as an example and carried out visual simulation.Firstlybased on the ionospheric model commonly used in engineeringthe calculation model of reflection height was established.The calculation modeldata sampling and visualization method of the smooth communication area of shore-ship communication with and without interference were proposedand the simulation was carried out based on the simulation platform.The realization effect showed that:It can meet the simulation requirementsand display the communication status more intuitivelywhich provides a method for equipment deployment and work parameter selection.
