Abstract

It has been over four years since the first SpecTIR Hyperspectral Airborne Rochester Experiment (SHARE) was conducted in 2010. As such, a second SHARE experiment was performed in 2012 using the same deployed target panels and HSI sensor (i.e., specifically related to the target detection experiment"). A suite of sensors were own over the target areas including multi- and hyperspectral imagers, as well as a LADAR sensor. Experiments were conducted to examine topics such as pixel unmixing, subpixel detection, forest health, and in-water target detection, to name a few. This paper's focus is on target detection of different colored panels deployed on different backgrounds viewed under different illumination conditions collected two years apart. Additionally, the calibration and reflectance retrieval of the data is also examined. Detection is on the standard reflectance product provided by the acquisition company. Results are illustrated in the form of ROC curves. Analysis was performed on (many) red and blue panels on backgrounds such as grass, gravel, and roof tar paper. The targets were in the open (i.e., fully illuminated), as well as heavy and light shadow, which were harder to discover than their open counterparts. Calibration of the 2012 data is good with some issues related to the 2010 data. Adjustments and corrections are discussed. Finally, discussion of where to obtain the free HSI and co-registered LADAR data set is discussed.
