Investigation of Target Detection Ability Using Spectral Signatures at Hyperspectral Resolution

摘要

This report addresses a variety of issues expected to influence the performance of airborne high spectral resolution (hyperspectral) Electro-Optic (EO) sensors when used as surveillance tools. Fundamental phenomenology issues have been considered with the breadth of this study ranging from investigation into the reflectance properties of materials, the influence of the atmosphere, and modelling of a sensor's performance. Simple data analysis and target detection assessment techniques including Target to Clutter Ratio measures and single and multiple band likelihood ratio detection' have been employed on an illustrative example. Initial results are promising, indicating high probabilities of detection with low false alarm rates for the test example.
