Scientific paper

Based on data from a Spacelab simulation mission onboard the CV-990 aircraft, a study is made of the so-called sky noise phenomenon which limits astronomical observations made by airborne telescopes. The infrared system consisted of a 32-cm f/8 telescope and a four-channel infrared photometer with a field-of-view selector. Noise was recorded in a 3-100-Hz band with the reference signal of the modulator. A phase-locked demodulation was then performed. The results indicate that sky noise depends on the field-of-view, chopping frequency, and wavelength. A turbulent model of the low stratosphere is described.
