The advanced technology land imaging spectroradiometer (atlis) is a small (0.04 M3) multispectral pushbroom imager designed to provide visible through shortwave (vswir) calibrated imagery for bands 1-10 of the baseline sustainable land imaging- technology (SLI-t) reference mission architecture. Atlis benefits sustainable land imaging by providing imaging spectroradiometry that meets or exceeds SLI-t reference mission architecture (RMA) parameters with an instrument that has 160X less volume and 16X less mass than the landsat 8 (L8) operational land imager (OLI) based on analysis completed in support of this proposal and during raytheon s sustainable land imaging (SLI) reduced instrument envelope (RIE) study for NASA gsfc and USGS in 2015. The intent of the proposed work is to build and test a single spectral band prototype atlis and demonstrate whether this wide field of view (wfov) fast optics small detector design approach with time delay and integration (TDI) to improve signal-to-noise ratio (SNR) achieves its promise by meeting or exceeding SLI-t vswir requirements for spatial and temporal coverage spatial performance radiometric SNR pixel-to-pixel uniformity saturation radiance polarization sensitivity radiometric stability dead inoperable and out-of-spec detectors. Period of performance is 19 months. Overall entry TRL is 3 with planned exit TRL of 5.
