Abstract

Modern scanning radiometers may produce sufficient data to completely inundate the data user. This paper describes such a radiometer, the methods used to select and distill the data, and data presentation formats. The instrument, the RM-20A Radiometric Measurement package, was the latest in a series of Lock-heed Missile & Space Company designed and operated satellite-borne infrared radiation measurement payloads. It was designed to gather information on geosphere and space backgrounds observable in MWIR and SWIR bands. Data rates were on the order of a megabit which dictated efficient data handling techniques in order to accommodate both overall background surveys and detailed analysis for phenomenology purposes. The instrument will be described only in detail sufficient to make data processing problems and objectives understandable. Emphasis is on the processing required to present and format the data for users with varied requirements. Topics covered include removal of instrument effects from the data, transformation and calibration of data-so that it can be compared with that gathered by other instruments, gray scale picture composition, transfer function and PSD generation and tracking of fixed and moving points by data processing.
