SCRIBE I Data Analysis,
Abstract
A LiN2 cooled cat's eye interferometer was flown on October 8, 1980, at Holloman AFB under the SCRIBE program. The post-flight data analysis can be divided into three major functions: (1) extraction of the interferogram data from the PCM telemetry record; (2) recovery of the spectral data from the extracted interferograms; and (3) analysis of the spectral data in terms of the atmospheric molecular parameters. The experiment was successful only during the first 20 minutes of flight. The balloon-borne instrument failed to produce the interferogram data after the balloon reached an altitude of 6 km. Our major effort up to the present can be summarized in the following four major categories: (1) to assemble the electronics interface to receive the output data of the PCM decommutator and to modify them in a proper format for the PDP11/20 computer; (2) to implement a scheme for recording the interferogram data extracted from the PCM record onto a digital magnetic recording tape; (3) to develop a scheme for processing the produced interferogram data recorded on a magnetic tape; and (4) to improve the analysis scheme on the recovered spectral data. Our efforts in all of these activities were successful in that we were able to obtain the atmospheric emission spectra from the telemetry record.
