  3. 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

    文中主要研究了電離層的三種影響：信號經過電離層傳播的群延遲引起的成像偏移；電離層的色散效應給線性調頻信號帶來二次相位誤差，導致圖像退化、失真；以及電離層的閃爍、湍流等不規則性引起的信號相位起伏。在此基礎上，比較分析了不同波段、帶寬條件下電離層的影響。
