Space based Hyper-Spectral Imaging Sensor


OBJECTIVE: Develop a space hosted Hyper-Spectral Imaging [1][2] sensor for Battlespace Awareness (BA), capable of targeting dynamic events and/or energetic battlefield objects (missiles, bomb blasts, aircraft, artillery fire). DESCRIPTION: This solicitation seeks development of an innovative hostable or free flyer space based hyperspectral imaging (HSI) sensor to increase target detection for the Battlespace Awareness and possibly Strategic Missile Warning mission areas. In particular, the SBIR will address development and application of HSI technologies to improve space-based target detection during suboptimal conditions such as viewing objects against sun-lit clouds. To perform the missions, the sensor will be required to image a large region of the earth by staring, scanning, or step-stare, with appropriate revisit rates. The effort will begin in Phase I with a Design Trade Study to address the mission requirements and how alternate HSI sensor system designs address the requirements. These trades should include field of view and sampling rate versus target velocity within the scene, focal plane array size, number of spectral bands, spatial resolution, scanning method (e.g. Fourier Transform/scanning Fabry-Perot, Cross Dispersive Prisms, dispersive linescan, etc.) and time to capture a spectra. The following key parameters may be used as initial goals to guide the design study: spectral range (1 - 5 microns), image size (512 x 512 or larger), spectral resolution (10 - 50 nm), and spectrum capture time (10 - 100 ms). The trade study should include predicted system performance. The design trade recommendations should be developed into a system design capable of performing the Battlespace Awareness and Strategic Missile Warning missions at representative altitudes. The technologies for the system design will be demonstrated first as a prototype HSI system for a ground or airborne proof of concept, and ultimately as a space qualified HSI sensor for space flight test. The Design Trade Study / System Design must address operating the HSI system in space. Space survivability in the orbital environment based on radiation hardening or design practices should be addressed. The technology shall be capable of supporting a 15-year mission in Geosynchronous Earth Orbit (GEO) or Medium Earth Orbit (MEO) and five years in Low Earth Orbit (LEO) after up to five years of ground storage. This project is ITAR restricted. No foreign persons as defined in appropriate laws and regulations governing ITAR may work on it. PHASE I: Address the design trades for a space-based HSI surveillance system. Trades should include field of view & sampling rate vs. target velocity within the scene, focal plane array size, number of spectral bands, spatial resolution, scanning method and time to capture a spectra. Design trades should be developed into a prototype design capable of performing the missions at representative altitudes. PHASE II: Fabricate and deliver the prototype sensor hardware for a ground or air based proof of concept. The work will address space qualified flight issues. The sensor hardware should address only the sensor system, but be capable of integration into the larger system foreoptics. The final report should include performance analysis (coverage and detection analysis) and should develop the process, procedures, and cost required to fabricate, test and deliver a turn-key space qualified HSI sensor. PHASE III: Build a space qualified HSI sensor & integrate into a space system for flight test. Military uses for this space-based HSI concept are battlefield surveillance and threat warning. Non-military uses for space-based HSI include combustion analysis. REFERENCES: 1.
