TRANSMISSION AND PROCESSING OF INFRARED SATELLITE IMAGERY IN OCEANOGRAPHIC STUDIES

A methodology for transmitting satellite information from shipboard receiving stations to onshore image processing centers is described, developed for the purpose of increasing the accuracy of water temperature and other oceanographic measurements taken by infrared scanning radiometers and promoting wider utilization of computers in image processing. Signals are recorded on magnetic tape, modulated, amplified to the normal operational range of a digital-analog signal transformer, and transformed into a sequence of eight-digit binary-decimal numbers, which pass through a photoelectric counter into computer memory. Infrared signals are isolated by an envelope demodulator in an early stage of the process. Translated from: Vestnik Leningradskogo Universiteta, 1985, No. 14, pp. 93-95.
