Abstract

Simulations of a technique to measure the spectral response functions (SRFs) of the Atmospheric IR Sounder (AIRS) detectors is presented. The AIRS detectors will be illuminated by the output of a blackbody modulated by a Fourier transform spectrometer. The resulting interferograms measured by the AIRS detectors are then Fourier transformed to produce SRFs. Separate simulations were performed for the central and wing SRF regions. The impact of resolution, finite field of view apodisation, and nonlinear detector response on the SRF full-width, central frequency, and wing response were investigated.
