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(tǒng)普遍采用濾波反投影 (FBP)重構(gòu)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(jìn)行圖像重建，因此具有更好的實(shí)時(shí)監(jiān)控性和更低的監(jiān)控成本，具有一定的現(xiàn)實(shí)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(yīng)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(lì)同軸線饋電,可以形成傾斜的波束,通過(guò)改變圓柱螺旋的參數(shù)可以調(diào)整其輸入阻抗以達(dá)到阻抗匹配的目的。
