摘要本研究內容是把物流管理中的條形碼技術應用到奶牛的個體識別上,通過圖像識別技術把塗制在奶牛背部的「等寬雙色條碼」轉換為系統的內部編號,再通過數據庫與奶牛的實際編號相關聯,結合其它的管理模塊來實現奶牛場的信息化管理。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。
