要約

A programmable matrix FPGA has been used to develop a Fourier-spectrometer, which can be applied in spectroscopic research of molecular radiation in the Earth atmosphere. The analysis bandwidth of such spectrometer is 160 MGz, the spectrum resolution is 39 kHz. The spectrometer is a real-time device that can continuously accumulate signal's spectrum virtually without losing the observation time. Its receiving systems can operate both in the compensation and modulation modes. Spectrometer functions are controlled by a PC interfaced with the local Ethernet. In this paper, we present the results of testing the spectrometer as a component of a receiving system while observing CO molecule radiation from the Earth mesosphere.
