According to the different scattering medium, scattering communication are generally divided into tropospheric scatter communications and ionospheric scatter communication.
根据散射媒质的不同，散射通信一般分为对流层散射通信和电离层散射通信。
Then we simulate echo interference route of the two ionospheric propagation mode, and the whole propagation loss of each path. Thirdly, we use the backward scattering energy algorithm to compute the ionospheric echo energy in the target unit distance.
仿真分析了两种电离层传播模式下电离层回波干扰路径，以及各个路径的传播损耗，并应用后向返回散射能量算法计算了目标距离单元内的电离层回波能量。
But the scattering effect of ionospheric irregularities has not yet been taken account.
但均未考虑电离层不均匀性对GPS系统误差的影响。
The computer modeling and simulation method of designing ionospheric coherent scattering radar antenna are addressed, using the NEC 2 codes.
讨论了借助计算机建模仿真的手段，利用磁矩代码NEC-2来进行电离层相干散射雷达天线阵设计的方法。
