Infrared Detections of Satellites with IRAS

摘要

The sky survey made by the infrared astronomical satellite (IRAS) in 1983 included observations of artificial earth satellites. The data base (with celestial objects removed) was correlated with the NORAD space catalogue to identify 452 satellites in orbit above the IRAS 900-km altitude. The flux density in three of the four wavelength bands has been analyzed to determine the temperature, emissivity, and absorptivity of the identified resident space objects.
