fan-beam

基本解释

Filter back projection (FBP) reconstruction algorithm is adopted by fan beam industrial CT systems.
扇束工业CT系统普遍采用滤波反投影 (FBP)重构算法。
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.
相比于基于图像重建的方法，本文提出的方法不需要进行图像重建，因此具有更好的实时监控性和更低的监控成本，具有一定的现实意义。
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.
研究了一种应用于卫星通信地面站的新型单臂平面螺旋天线,该天线采用圆柱螺旋激励同轴线馈电,可以形成倾斜的波束,通过改变圆柱螺旋的参数可以调整其输入阻抗以达到阻抗匹配的目的。
