Paper Abstract

The absolute spectral radiant exitance of IR signatures from countermeasure flares for mid-IR was experimentally validated by using an optical emission spectrometer. A 256-array PbSe detector was installed to analyze the mid-IR emission spectrum of four IR signatures from countermeasure flares and propellants. We could evaluate the performance of the optical emission spectrometer and verify its usefulness in the field of IR countermeasures. The spectral response of the optical emission spectrometer was calibrated using a directly heated graphite blackbody; in addition, the total uncertainty was analyzed. The absolute amount of emissions of four IR signatures was calculated and compared.
