Space developments at SOFRADIR for Sounding applications

摘要

SOFRADIR is one of the leading companies involved in the development and manufacturing of infrared detectors for space applications. Among them, meteorological applications, meaning imagery and spectrometry, require detectors operating from medium wavelength up to high wavelength bands (around 14 μm) while having high radiometric and imaging performances. The purpose of the paper is to focus on developments made at SOFRADIR in order to answer specific needs of the infrared sounding instruments MTG IRS. Analysis of the main driven performances and constraints is presented. Then the proposed design and solutions are described and first results of the developments in progress are presented.
