fan-beam

基本解釋

Filter back projection (FBP) reconstruction algorithm is adopted by fan beam industrial CT systems.
扇束工業(yè)CT系統普遍采用濾波反投影 (FBP)重構算法。
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.
相比于基于圖像重建的方法，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(jiān)控性和更低的監(jiān)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.
研究了一種應用于衛(wèi)星通信地面站的新型單臂平面螺旋天線,該天線采用圓柱螺旋激勵同軸線饋電,可以形成傾斜的波束,通過改變圓柱螺旋的參數可以調整其輸入阻抗以達到阻抗匹配的目的。
