摘要

在多模模式下，对侧向散射应答信号的模式特性、频率特性以及群距离特性进行了仿真分析，并与获取的试验数据进行对比分析，验证了基于点到点的电离层侧向散射特性与两条链路上电离层特性关系，即电离层侧向散射的模式是侧向散射两条链路模式的组合，每一个组合模式的最小可用频率与两个模式最小频率的较大值相对应，组合模式的最大可用频率与两个模式最大频率的较小值相对应，每一组合模式的群距离是两种组合模式的群距离的和，为后续电离层特性的研究，以及电离层侧向散射对目标探测、多基地定位、工作参数选择等具有重大的意义.

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.
