This paper presents the results of the modelling of the spectral filtering system of a new type of video spectroradiometer-gas viewer intended for monitoring the spatial distribution pattern of the anthropogenic gases NO2 and SO2 in the near-earth atmosphere. The system is based on the combined use of interference-polarization and narrow-band interference filters.
