  1. The simulation results show that, image will be severely degraded by phase fluctuations at typical conditions of the ionosphere, and can be well focused after calibration

    模擬結果表明，電離層引起的相位起伏對成像影響較大，校正後可得到比較滿意的結果。
  2. Laser - controlled ground leveling technology is the combination of normal ground leveling technology and laser control technology. the leveling shovel is driven by a tractor and its rising and dropping is controlled by automatic electric system, so the shovel will always operate in the same level. this leveling system also can be installed together with bulldozer and forklift

    激光控制土地平整技術是高科技激光控制技術與常規機械平地技術相結合的土地平整新技術，是由拖拉機帶動平地鏟，對土地進行平整，它的電控系統是對鏟土機的升降實時調整的自動控制技術，是鏟土機始終在同一水平面工作，該系統還可以安裝在推土機、鏟車上，可以廣泛地應用於新建公路、廣場、運動場以及房屋基地的平整，對于起伏不大的場地可以一次性平整到位，大大提高了生產效率和土地平整精度。
  3. To correct these effects, two methods were introduced in this paper : using weighted function to constrain second phase error caused by dispersion, and utilizing pga algorithm to reduce the phase perturbation due to the irregularities of the ionosphere

    本論文介紹了兩種校正方法：利用加權函數抑制色散效應引起的二次相位誤差，以及使用相位梯度自聚焦演算法較正由電離層的不規則性引起的信號相位起伏。
  4. 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。
