  1. By computing the between two resolution units, we can estimate terrain azimuthal slopes and derive estimate of terrain elevation. the terrain contour is determined uniquely by ay / from azimuth slop on range gates. american began to study p - sar three - dimensional images technology in 1990s

    Schuler已經證明,對於一個均勻分佈場景, sar圖像上兩個相鄰分辨單元的極化橢圓方向角偏移量,與地形方位向坡度的對應關系是線性唯一的,地形方位向的傾斜度可以通過解唯一地被測定。
  2. 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。
