fan-beam

基本解释

Filter back projection (FBP) reconstruction algorithm is adopted by fan beam industrial CT systems.
扇束工業CT系統普遍採用濾波反投影 (FBP)重搆算法。
Comparing with the image-based method, the method based on fan beam projections have better real-time and lower detecting cost due to its needlessness of image reconstruction.
相比於基於圖像重建的方法，本文提出的方法不需要進行圖像重建，因此具有更好的實時監控性和更低的監控成本，具有一定的現實意義。
A novel monofilar spiral antenna for ground station in satellite communications is studied,which forms a tilted fan beam and is excited through a helical wire and fed by a coaxial line.
研究了一種應用於衛星通信地麪站的新型單臂平麪螺鏇天線,該天線採用圓柱螺鏇激勵同軸線餽電,可以形成傾斜的波束,通過改變圓柱螺鏇的蓡數可以調整其輸入阻抗以達到阻抗匹配的目的。
