Abstract • The convergence of hyperspectral imaging aboard UASs is
occurring at a very rapid pace • Hyperspectral imaging within the remote-sensing realm is
proving to be a go-to instrument • It allows for excellent identification and discrimination of
chemical/spectral characteristics that might not be visible any other way
• Integrating these specialized instruments aboard any type of
UAS is challenging

• Lab spectrum for MES plotted in RED vs detected spectral signatures for MES in-scene
• Detection 1 depicts a much higher concentration of the MES chemical than Detection 2
• Detection 3 depicts a higher concentration than Detection 2 but lower than Detection 1

Summary • Reductions in UAS and Hyperspectral SWaP and price have
opened many new applications for remote sensing
• Integrating specialized Hyperspectral instruments aboard any type of UAS is challenging and requires technical depth and breadth
• Hyperspectral imaging allows for excellent identification and
discrimination of chemical/spectral characteristics that might not be visible any other way
