arXiv:2611.08927v1 Announce Type: new Abstract: Discerning core performance bottlenecks in hyperspectral target detection is highly challenging given the complex interplay between sub-systems of the imaging chain (scene, atmosphere, sensor and processing). Prior sensitivity and limitation studies offer narrow insights applicable to specific system configurations. To address the need for broader generalization, an analysis framework was constructed to quantify limitations from large ensembles of model scenarios. Key components of the framework include the use of canonical scene representations and the log-weighted area under the ROC curve (wAUC), a metric well-suited for rare target detection. By analyzing thousands of scenarios, parametric thresholds were quantified where detection performance degrades, corresponding to "knees" in performance curves. A knee significance score (KSS) is introduced to assess the relative importance of these thresholds. The framework an airborne VNIR sensor implanted in 28,000 scenarios using seven system parameters spanning the scene, atmosphere and sensor. Results suggest that aerosol visibility in the 2-6 km range is the dominant limiter in detection, followed by subpixel target percentages of 15-35%, and background clutter modeled using a t-distribution with 3-5 degrees of freedom.
