Abstract

The ARPA Mai Optical Station (AMOS) is an advanced electro-optical research and development facility located atop Mt. Haleakala at an altitude of 10,000 feet on the Hawaiian island of Maui. Co-located with AMOS and sharing common support facilities is the Maui Optical Tracking and Identification Facility (MOTIF), a Spacetrack unit of the Strategic Air Command (SAC). One of the prime sensors at the site is the AMTA, a long-wave infrared (LWIR) radiometer, which is routinely used for making infrared radiance measurements on exoand endoatmospheric targets and for making phenomenological measurements on the intervening atmosphere. The AMTA used one of the two MOTIF 1.2 meter cassegrain telescopes as its collecting aperture to obtain LWIR measurements in any of seven discrete spectral bands from 3 urn to 21 μm wavelength. This paper discusses the AMTA sensor instrumentation, data collection and recording schemes, and calibration techniques employed in preparation for IR data collection activity. Ongoing developments providing for an on-site infrared data reduction enhancement capability will also be discussed, as will the development of a new IR spectral radiometer for the AMOS 1.6 meter telescope.
