Paper Abstract

Range performance of an imaging system is a key factor for an infrared search and tracking system with a purpose of detection, recognition and identification. Therefore, the prediction of the expected range performance is of utmost importance. The range prediction includes many variables that affect the outcome. Wavelength is one of the most important parameters because it has an enormous effect on range, but detector technology directly related to range performance. In this study, MWIR and LWIR imaging systems in certain configurations are modelled and analyzed in terms of range. The imaging system is modelled taking into account the properties of the detector and the optics, while the atmospheric conditions is modelled using MODTRAN. Analytical expressions for detection, recognition and identification ranges with respect to Johnson criteria for different target types are derived. The effects of the given parameters to the range performance are examined and a comparison between the different wavelengths is discussed.
