Abstract : Infrared measurements of auroral, airglow and artificial source emissions were planned and performed. The measurements were made with a near infrared (NIR) radiometer system and a cold chopper interferometer-radiometer system operating from an AFCRL KC-135 aircraft. Some support measurements were also performed from a ground-based station. These measurements were necessary for rocket support and future aircraft-borne measurement planning planning and correlation. To accomplish the desired measurements, it was necessary to periodically perform calibrations, inspections, and maintenance on the instrument systems. Optional modifications were designed and constructed for the NIR system to allow measurements of target sources in bright backgrounds and to allow narrow field of view measurements. In addition, a radiometer was designed and constructed to make infrared measurements at wavelengths from 2.9 to 4.9 micrometers. Finally, a design study of a radiometer for wavelength measurements from 1.4 to 4.9 micrometers was performed. (Modified author abstract)
