Demonstration of Airborne Wide Area Assessment Technologies at Pueblo Precision Bombing Ranges, Colorado. Hyperspectral Imaging, Version 2.0.

摘要

Hyperspectral imaging (HSI) technology was demonstrated as part of ESTCP's Wide Area Assessment Pilot Program at the Pueblo Precision Bombing Range No. 2 in Colorado. HSI sensors were deployed from fixed-wing platforms as part of the high airborne data collection and analysis for WAA and augmented the analysis of other high airborne datasets collected at the demonstration site, including LiDAR, large scale orthophotography, and synthetic aperture radar (SAR). Although the HSI sensor by itself would not out-perform the LIDAR/Orthophotography sensor combination for general WAA site characterization, the demonstration showed that HSI imagery can be used for detecting and extracting large munitions-related features such as target aiming features, and can sometimes detect landscape disturbance patterns including surface disturbance features difficult to observe in other datasets. In addition, the HSI datasets were used in a multiple-sensor fusion process to perform false- alarm reduction through the generation of detailed vegetation models used to discriminate metal from vegetation in SAR surface object detections.
