动态成像技术
The On The Fly Imaging Technique
摘要:
飞行中(OTF)成像技术使单碟射电望远镜能够以更高的效率和精度构建天空小区域的图像。本文介绍了光学传递函数成像技术的实际应用。通过例子,OTF成像技术在NRAO 12米望远镜的实施进行了描述。数据采样,图像形成和多普勒校正的具体要求进行了讨论。
英文摘要:
The On-The-Fly (OTF) imaging technique enables single-dish radio telescopes to construct images of small areas of the sky with greater efficiency and accuracy. This paper describes the practical application of the OTF imaging technique. By way of example the implementation of the OTF imaging technique at the NRAO 12 Meter Telescope is described. Specific requirements for data sampling, image formation, and Doppler correction are discussed.
