    • GOES advanced sounder design study 

      Bicknell, William; Kerekes, John; Ryan-Howard, Danette (The International Society for Optical Engineering (SPIE), 1996-08-07)
      Interim results of a current study on upgrading the geosynchronous operational environmental Satellite (GOES) infrared (IR) sounder are presented. Considered are a 15 cm diameter telescope to reduce instrument size and ...
    • Parametric analysis of target/decoy performance 

      Kerekes, John (The International Society for Optical Engineering (SPIE), 1991-04-01)
      As infrared sensing technology matures and the development of space-based optical sensors becomes feasible, interest has grown in protecting both ballistic and orbiting objects from detection by optical sensors. Such ...
    • Spectral quality requirements for effluent quantification 

      Czerwinski, Richard; Farrar, Kristine; Griffin, Michael; Kerekes, John (The International Society for Optical Engineering (SPIE), 2004-08)
      Based on simulated atmospheric and sensor effects, we identify spectral resolution and per-channel signal-to-noise ratio (SNR) requirements for thermal infrared spectrometers that allow effluent quantification to any ...
