Paper Abstract

Future GOES sounders will likely require increased spectral resolution and number of channels in order to meet the sounding vertical resolution and accuracy specifications set forth by the science community. The sensor technology and systems group at MIT Lincoln Laboratory has pursued the use of a high resolution interferometer (GHIS) is order to meet these spectral needs. This paper will focus on the electronics and signal processing necessary for achieving the noise fidelity, dynamic range and data rate constraints for the GHIS instrument. This will include the absolute fringe counting interferometer, analog filtering, A/D conversion, and digital processing. The paper will highlight techniques for reducing the interferometer dynamic range and data rate in order to simplify a GHIS flight design.
