摘要

由于微带器件的发展，微波元件的数学建模和自适应数字技术的使用，CTS(啁啾变换光谱仪)的分辨率和动态范围得到了改善。CTS是GREAT(德国太赫兹频率接收器)的一部分，GREAT是机载天文台SOFIA(平流层红外天文观测台)上的第一代高分辨率双通道外差仪器。

Microwave Technologies for SOFIA's High Resolution Spectrometer

Improvements in the resolution and the dynamic range of the CTS (Chirp Transform Spectrometer) were achieved thanks to the development of microstrip devices, mathematical modeling of microwave components and the use of adaptive digital technologies. CTS is part of GREAT (German REceiver At Terahertz frequencies), a first-generation dual-channel heterodyne instrument for high-resolution spectroscopy aboard the airborne observatory SOFIA (Stratospheric Observatory for Infrared Astronomy).
