Abstract

Advances made over the past decade in multispectral and hyperspectral imaging systems, have led to a wide range of new remove sensing capabilities, including the ability to detect and image chemical vapors in the atmosphere. This sensor has application in the detection and monitoring of chemical weapons, as well as environmental pollution monitoring. Key to the continuing development of this technology is accurate and temporally stable radiometric calibration. This paper presents an overview of the system level radiometric calibration approach used for the SAFEGUARD multispectral infrared line scanner. This approach includes radiometric calibration of the sensor at the aperture, corrections for atmospheric effects and group truth validation.
