Abstract:In multi-mode mode,pattern characteristics,frequency characteristics and distance characteristics of the ionosphere side scatter response signals are simulated.Comparing with the obatained experimental data,ionospheric side scatter characteristics and the relationship between the ionosphere characteristicson of the two links based on point-to-point are verified.The mode of ionospheric side-scattering is a combination of two link modes of side-scattering.The minimum available frequency of each combination mode corresponds to the larger value of the minimum frequency of the two modes.The maximum available frequency of the combination mode corresponds to the smaller value of the maximum frequency of the two modes.The group distance of each combination mode is the sum of the group distances of the two combination modes.It is of great significance,for the study of subsequent ionospheric characteristics ionospheric side scattering for target detection,multi-base positioning,operating parameter selection,etc.
