Multiband chirp transform spectrometer for the microwave remote sensing of middle atmospheric trace gases

摘要

Abstract: A new generation of submillimeter wave limb sounders require multiband real time spectrometer backends with high constraints on mass, size and power consumption. A new concept, the multiband chirp transform spectrometer (MBCTS) was developed for this purpose. The MBCTS was chosen to be suitable for the Advanced Microwave Atmospheric Sounder (AMAS), a European instrument, which is currently in the breadboarding phase and is planned to be flown in 1999. The basic concept and the development status of the multiband CTS are described. !9
