ionosphere error 解釋
電離層誤差
  • ionosphere : n. 【物理學】電離層 (=ionized layer)。adj. -spheric (= ionosphere layer).
  • error : n. 1. 錯誤;失錯。2. 謬見,誤想;誤信;誤解。3. 罪過。4. 【數學】誤差;【法律】誤審,違法;(棒球中的)錯打。adj. -less 無錯誤的,正確的。
  1. 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。
  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。
  3. According to the high spatial correlativity of the ionosphere contamination, then the rank one phase error estimation ( rope ) auto - focus method in imaging radar is suitably modified and applied to the ionosphere decontamination of hf radar echoes

    根據電離層污染具有高度空間相關性的特點,將成像雷達中的秩一相位誤差估計聚焦方法適當修正後應用於高頻雷達回波信號去電離層擾動污染。
  4. This method is based on the bent ionosphere model and the coefficient of dynamic correction is introduced into traditional cosine correction model to achieve dynamic correction of ionosphere delay. so the position error of over correction can be overcomed

    該方法以bent電離層模型為基礎,在餘弦電離層修正模型的基礎上,引入動態修正系數,從而克服了採用通常修正方法帶來的過修正誤差。
