电离层传播 meaning in Chinese

iono here propagation
ionosphere propagation
ionospheric propagation

Trans - inospheric propagation
越电离层传播
Hop ionospheric propagation
跳电离层传播
On the following , on the basis of formulas given above , three kinds of effects due to ionosphere are presented : image shift due to group delay which was caused by the difference between the group velocity and the velocity of light in the ionosphere ; image distortion due to ionospheric dispersion which can create second phase error of lfm signals ; the last , the phase perturbation caused by the irregularities of the ionosphere can reduce the coherent length and affect azimuthal resolution
文中主要研究了电离层的三种影响：信号经过电离层传播的群延迟引起的成像偏移；电离层的色散效应给线性调频信号带来二次相位误差，导致图像退化、失真；以及电离层的闪烁、湍流等不规则性引起的信号相位起伏。在此基础上，比较分析了不同波段、带宽条件下电离层的影响。
