Paper Abstract

The ATLAS (Airborne Terrestrial Applications Sensor) is a 15-channel multispectral scanning imager, currently under development for NASA's Commercial Remote Sensing Program Office. The sensor package utilizes a rotating linescan mirror, and a modified Dall-Kirkham telescope with a 7.5-inch clear aperture and 2.0 mrad ifov. Scan rates are adjustable from 6 - 50 rev/sec, with a total of approximately 73 degree(s). Three spectrometers with grating dispersive elements are used to provide wide spectral coverage. Blackbody sources (hi/lo) and a modified integrating sphere source, built into the scanhead, are employed to provide in-flight radiometric calibration data for quantitative inference of ground scene temperatures and radiance values. In this paper, the overall design of the ATLAS scanner system is reviewed. Results of spectral response, NETD, NER, and MTF calibration measurements are presented for each channel. Additionally, some initial ATLAS flight test data and analysis are described, including SNR, uniformity of TIR data over water, overall image quality and other results.
