  1. The ionosphere is a complex medium, which is aeolotropy, asymmetry, dispersive and changes randomly with time. in order to improve the communication quality of the shortwave that depends on the ionosphere, we should have aknowledge of the current condition of the ionosphere in real time. the backscatter sounding of high frequency can diagnose the real - time channel characters for shortwave communication or hf radar, which is great assistant to shortwave communication and hf radar

    電離層是隨機時變，各向異性，非均勻、色散的復雜介質。為了保證依賴于電離層進行的短波通信質量，必須了解電離層的實時狀態信息。高頻返回散射探測可以實時監測與短波通信或高頻天波雷達相關的天波傳播通道的狀態，對短波通信和天波雷達工作起了重要的輔助作用。
  2.

  7. 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。
