超导体-绝缘体-超导体（SIS）混频器和热电子-测辐射热计（HEB）等微波外差接收技术的发展，为探测大量的大气微量成分提供了可能，而这些成分在以前是无法探测到的。同时，对光谱仪的功能性能要求也越来越高。啁啾变换光谱仪（CTS）满足了这些要求，因为它具有高分辨率、稳定性、线性度和动态范围，并且由于其非常低的质量和功耗，在未来的星载应用中具有很大的发展潜力。介绍了马克斯-普朗克航空研究所（MPAE） CTS的发展状况，并讨论了可能的星载应用。
The development of microwave heterodyne receiver technologies like Superconductor-Insulator-Superconductor-(SIS) mixer and Hot-Electron-Bolometer (HEB) offers the possibility to detect a large number of minor atmospheric constituents, which have been under the detection limit before. The requirements on the functional performance of spectrometers have increased at the same time. The Chirp Transform Spectrometer (CTS) fulfills these requirements, because of its high resolution, stability, linearity and dynamic range and has a large development potential for future spaceborne applications due to its very low mass and power consumption. The development status of CTS at the Max-Planck-Institut fur Aeronomie (MPAE) will be described and possible spaceborne applications will be discussed.
