Advanced Algorithms for Next Generation Wide Field-of-View (WFOV) EO/IR Staring Sensor Exploitation

ABSTRACT: Frontier Technology Inc, (FTI) proposes to improve advanced algorithms in hyper-temporal imaging (HTI) to provide new capabilities in target discrimination in challenging environmental conditions. Specifically, we propose to develop a computationally efficient algorithm for target detection and discrimination under optically obscured geometries and in closely spaced formations (within clouds or under clear sky). HTI opens new dimensions in orbital or aerial overhead persistent infrared surveillance, especially in these two challenging regimes. We are proposing to take advantage of advances in focal plane technology that allows sections of the array to operate at very fast frame rates by developing novel algorithms and approaches to enable detection of target launches beneath optically thick cloud layers and to discriminate and track multiple closely-spaced objects on a subpixel basis. These novel algorithms are based on our previous work in Tabular Nearest Neighbor Encoding and Fourier Transforms. Using these techniques, parts of the focal plane upon which are projected the areas of interest that are obscured by clouds could be operated at very high frame rates, while the remainder of the array could continue in its current, lower frame rate, operating mode. BENEFIT: The research objectives of this Phase I SBIR are in line with FTI"s goals to continue adding new capability to our commercial I-SAT software, invest in our GPU analytical code base, and most importantly, extend our development into algorithms and tools that support the next generation of EO-IR sensors and missions. Hyperspectral and hypertemporal analysis and visualization capabilities are a growth focus for FTI. There is wide demand in the government sector for more rapid and computationally efficient exploitation of WFOV imagery to provide operationally-responsive information to the warfighter. The market for this technology is also ongoing: in order to maintain a constellation of persistent surveillance coverage, new WFOV sensors will need to be continually developed and flown.
