The Department of Defense (DoD) is seeking proposals for a compact midwave infrared hyperspectral imager for attritable platforms. The objective is to develop a midwave infrared (MWIR) hyperspectral imager capable of covering a 3-5 um wavelength range with at least 250 spectral bands. MWIR HSI has traditionally received less attention due to complications with solar reflection and self-emission affecting target detection, but advancements in non-linear detection algorithms have mitigated these concerns. The proposed system should have a ground sample distance (GSD) of no more than 3m and a noise equivalent spectral radiance (NESR) of no more than 2 u-flicks averaged across all bands between 4.5 and 5 um. The project will be conducted in three phases: Phase I involves developing plans and concept designs, Phase II focuses on refining the concept and developing a prototype, and Phase III involves adapting the design for an attritable platform and conducting flight testing. The solicitation is open until October 18, 2023. For more information, visit the DoD SBIR 23.3 BAA solicitation on grants.gov.
