Ecological Systems and Devices Annotation << Back Ecological optical monitoring of circumterrestrial space pollution Murtazov A.K., Voskresensky A.V., Kolosov D.V., Titov P.V. The principles for organizing ecological monitoring of the lower circumterrestrial space pollution are examined. The most perspective for large-scale use are CCD-based optical systems. Calculations of expected dimensions for objects of natural and technogenic origin that can be found by these systems are specified.
